During his murder trial, prosecutors described Saadallah’s attack as "ruthless and lethal".

At around 18:45 BST witnesses saw a lone knifeman target a group of people in Forbury Gardens near Reading town centre.

Friends James Furlong, 36, Dr David Wails, 49, and Joseph Ritchie-Bennett, 39, were fatally stabbed.

Three others - Stephen Young, Patrick Edwards and Nishit Nisudan - were also injured.

Saadallah shouted "Allahu Akbar [God is greatest]" as he attacked and again as he ran away, throwing away the 8in (20cm) knife as he was pursued by an off-duty police officer.

At 18:56 the first emergency call was made to Thames Valley Police.

Chief Constable John Campbell said officers arrested a man within five minutes of the call.

CCTV footage was played at Khairi Saadallah's sentencing hearing in 2021, showing him running away from the murder scene.

Videos also revealed his movements before and during the day of the attack.

Saadallah could be seen smashing his phone, putting a knife in his pocket and then fleeing the park in Reading, before later being chased down and arrested in a street.

• June 19: Saadallah is caught on CCTV at Morrisons supermarket buying a knife
• On the same day a crisis team visits after he contacts them, but when they arrive, he does not open the door. The visiting officer alerts his mental health team after becoming concerned about comments Saadallah made about "magic"

• Later that day local police visit Saadallah at a flat in Basingstoke Road, Reading, after his brother calls to raise concerns about his mental state
• Body-worn video from the two-minute encounter shows Saadallah reassuring the officers, who asked how he was feeling and if he had enough food. A carrier bag containing a knife was visible on the floor behind Saadallah

In the days before the attack on 20 June 2020, Khairi Saadallah began to plan.

• June 15: He searches the internet with the question "Is Corona a sign of the end of the world" and looks up images of military activity in Libya and bodybags. He also accesses images of Forbury Gardens
• June 17: Saadallah is seen on CCTV footage carrying out "reconnaissance" of Forbury Gardens
• June 18: He accesses a website with the flag associated with the so-called Islamic State and has contact with his probation officer

Judge Coroner Sir Adrian Fulford said MI5 had "no credible information" that could have prevented Khairi Saadallah launching his Reading attack in June 2020.

The agency also did not obtain any intelligence that he was planning to travel back to Libya.

An unnamed MI5 manager told the inquest in February there was no "proportionate action" that it could have taken to change the outcome.

Judge Coroner Sir Adrian Fulford said the reports shared between authorities were "markedly deficient" and left police and others unclear about the risk Khairi Saadallah posed.

A failure to share details included information throughout 2019 - and provided a "critical backdrop" in the days before he killed in 2020.

Other details failed to record his association with Omar Brooks, also known as Abu Izzadeen (pictured), who he met in HMP Bullingdon, and possible previous membership to terrorist groups in Libya.

The court also heard Khairi Saadallah was referred by various professionals to the government’s Prevent programme four times - it aims to stop people developing extremist or terrorist mindsets.

Not one of those referrals was progressed, because Saadallah wasn’t assessed as being of a high enough risk.

Sir Adrian Fulford concluded this was because of "failings in obtaining the full intelligence picture and in the analysis of that intelligence" as well as failures in procedure, training and supervision.

One intelligence assessment carried out was labelled "simply inadequate" by the judge coroner.

He told the court neither Prevent, nor Pathfinder, nor Mappa, provided "effective intervention" to "address the threat he posed as a lone actor".

When the judge coroner went over Khairi Saadallah’s mental health history and his contact with countless mental health services, what emerged was a picture of a highly unstable man with violent tendencies and a terrorist mindset - being pinged between pillar and post.

The court heard he was "caught in a catch 22" - with no continuity of care, "mental health referrals bounce from one service provider to another".

One probation officer was singled out for praise though - for her tireless attempts to "master a fragmented system" when he was released from prison, leaving her frustrated that "nobody in mental health services were prepared to deal with him".

There were mentions of very competent professionals being involved with Saadallah - but they either hit resistance or were not given all the information they needed to make accurate judgements.

Back to today's inquest, Judge Coroner Sir Adrian Fulford said programmes, including Prevent, did not provide "any intervention of utility during stages in this case" when Khairi Saadallah was in the community or in prison.

Systems were "under resourced and not integrated". There were about 90 records relating to Saadallah.

They included details of him possessing weapons, extremism and self-harm.

In the month before the Forbury Gardens attack in 2020, officials were working to deport Khairi Saadallah back to Libya.

• May 28: Home Office staff email Thames Valley Police saying they planned to deport Saadallah, but were unable to "until the impending charges had been dealt with". He was facing a trial accused of eating a mattress at a police station and spitting at an officer in July 2019
• June 1: The charges are dropped
• June 5: Saadallah is released from HMP Bullingdon
• Two weeks before the attack, Saadallah receives a letter stating the home secretary decided his deportation "is conducive to the public good" - but it was not legally possible given conditions in Libya

In 2019, Khairi Saadallah was declared a "subject of interest" by MI5, but months later he became a "closed subject of interest", the inquest has previously been told.

The security service had been informed Saadallah might wish to travel to Syria - but, after an assessment, he was discounted as a threat and not investigated.

By that time, he had spent years in and out of prison for offences including assaulting police officers and emergency workers, racially aggravated harassment and possessing knives.

In October of 2019, he was jailed for 25 months and 20 days for a string of crimes, but the sentence was reduced in March 2020 - months before the Forbury Gardens attack - following an appeal.

Khairi Saadallah has six convictions for 11 crimes between June 2015 and January 2019.

In 2017, he was in jail at HMP Bullingdon, at the same time as prominent radical preacher Omar Brooks - also known as Abu Izadeen - who is associated with the banned terrorist organisation Al-Muhajiroun.

During Saadallah's sentencing, the prosecution said he was observed to be "keen to associate" with Brooks and was "impressionable and volatile".

Khairi Saadallah's time in the UK has been well documented.

In 2011, he is said to have joined a terrorist group in Libya, which is proscribed in the UK, during the Arab Spring uprising against Muammar Gaddafi's dictatorship.

The inquest heard Saadallah fled the group when he was asked to engage in torture.

In 2012, he arrived in the UK as an asylum seeker.

From 2013 until 2020, he was repeatedly arrested and convicted of various offences, including theft and assault.

Following the 2020 attack, tributes were paid to the three men.

James Furlong, David Wails and Joe Ritchie-Bennett were regular customers at a pub near Forbury Gardens, where they were murdered.

Local residents held silences and laid flowers around the town.

The inquest has paused for a lunch break and will resume at 13:40 BST.

So far today Judge Coroner Sir Adrian Fulford has identified "a number of significant matters that, had they been handled differently", could have prevented the attacks that cost the lives of three men in Reading in June 2020.

Sir Adrian will continue to deliver his findings at the Old Bailey in London this afternoon.

Sir Adrian said two counter-terror programmes, including Prevent, external, were not aware of Saadallah's release from HMP Bullingdon on 5 June 2020.

He said Saadallah was also judged to be suitable for enrollment on a counter-terror programme while he was in prison in December 2019.

But he was not because of the time left on his sentence and because inmates at HMP Bullingdon were not offered it.

Before his release from HMP Bullingdon in June 2020, Saadallah was "relatively stable" over April, May and June and more intervention "may have been" taken, Sir Adrian said.

However, while he had been held there he told people he wanted to stab someone.

That crucial detail was not included in intelligence reports until two days after he had killed in Reading.

Saadallah was in prison at HMP Bullingdon in Oxfordshire (pictured) in December 2019, the inquest hears.

The CEO of a charity that had helped him told authorities he feared "disastrous consequences" if Saadallah did not get appropriate help.

Nick Harborne, the chief executive of Reading Refugee Support Group, told authorities he felt Saadallah was "extremely vulnerable".

The conclusions of the judge coroner, Sir Adrian Fulford, so far have been damning.

He identified failures by "one or more identified state agents" and organisations to protect lives.

He said Saadallah was a "known extremist" with a "terrorist mindset", and his "settling on jihad as a solution to his turmoil" could have been "avoided".

We’ve heard many details about Saadallah’s life.

He’s a former child soldier from Libya, who fought with extremist Islamic militia during and after fall of the Gaddafi regime.

Since his arrival in the UK as an asylum seeker, he had frequent contact with numerous authorities.

He told professionals he had killed people, tortured people, that he wanted to kill others, could envisage killing others and then killing himself.

Sir Adrian said, with "extremism on one hand and mental health on the other" all key agencies should have been informed, and should have considered, the "totality" of all background information about Saadallah.

That was "crucial" in assessing the risk he posed. The fact that continuing intelligence collected on Saadallah was "not fully assessed" fell far below necessary standards.

The inquest has heard about Saddallah's long history of mental health problems and alcohol and drug abuse.

That included assessments that found he was "very ill" in 2018.

Judge Coroner Sir Adrian Fulford said Saddallah was discharged from community mental health services in Berkshire in 2019 despite the "strength of feelings" from some professionals.
