Chief Constable Sawyer was asked by a member of the media whether Davison was receiving treatment for mental health issues.

He said police would investigate this, but that "clearly this was an extraordinarily unusual" act by a human being.

Mr Sawyer said he could not say at this time whether or not mental health issues were involved.

He said the coroner would also be asked to investigate this.

Chief Constable Sawyer said Davison's motive was unknown at present, but police were currently "not considering terrorism or a relationship with any Far Right group or any other such group".

Davison's social media activity will form part of the police investigation, he added.

Jake Davison held a licence for a firearm, Chief Constable Shaun Sawyer has said.

However, he would not confirm whether this was the weapon used in the shooting.

Eyewitnesses described the gun used as a pump-action shotgun, but police would not confirm if this was the case.

The weapon recovered from the scene will be forensically examined.

Chief Constable Sawyer continued by saying that eyewitnesses described the firearm used by Davison as a "pump-action" firearm.

He confirmed a firearm had been found at the scene and will be forensically examined, but that police are not yet describing the weapon as a "pump-action firearm" although "clearly multiple shots have been fired" during the six-minute period.

Mr Sawyer added there are 13 scenes and "potentially more scenes" and that members of the public were evacuated from the scene overnight.

He confirmed "five people of Plymouth have lost their lives overnight and Mr Davison himself, including a particularly young child".

Officers are not naming the victims at this time to protect their wider families, employers and others affected across the UK, he added.

Chief Constable Shaun Sawyer said after Jake Davison shot and killed his first victim in a house on Biddick Drive, he moved into the street where he shot and killed a "very young girl" and her male relative.

Afterwards he aimed and shot at two local residents, a man and woman, who received significant but not life threatening injuries and are now being treated in hospital.

Mr Sawyer said Davison shot and killed a man in nearby parkland.

He then shot a woman in Henderson Place who later died at Derriford Hospital despite the best efforts of first aiders at the scene.

Eyerwitnesses then said the shooter turned the gun upon himself, the Chief Constable added.

The press conference has begun at Crownhill Police station.

Devon and Cornwall Police Chief Constable Shaun Sawyer says updates on the investigation will be released to the public and the media throughout the coming hours and days.

He says the events are "particularly traumatic" for people and urged people to contact victim support if they needed to.

Mr Sawyer says police received a "considerable" number of "multiple calls" from the public at 18.11 BST on Thursday, and they were assessed, and it was later revealed shots were fired.

He says armed and unarmed officers got to the scene at Biddick Drive within six minutes.

He confirms 22-year-old Jake Davison had killed a woman at an address, but says he won't reveal that address as officers are still contacting relatives of the deceased lady.

A press conference led by Devon and Cornwall Police Chief Constable Shaun Sawyer is expected shortly, to update the public on the latest information about the shooting.

In videos posted online weeks before the shooting – and since removed by YouTube – the Plymouth gunman Jake Davison spoke of being “beaten down” and “defeated by life”, but compared himself to the Terminator.

He said he was socially isolated, struggled to meet women and made references to “incels” – the misogynistic online groups of “involuntary celibate” men, who blame women for their sexual failings and who have been linked to a number of violent acts around the world.

Signing off on the 11-minute video, which appears to be the last he posted, Davison said: "I know it's a movie but I like to think sometimes I'm the Terminator or something. Despite reaching almost total system failure he keeps trying to accomplish his mission."

Devon and Cornwall Police and Crime Commissioner Alison Hernandez has pleaded with people not to share videos of the incident.

Speaking to Radio 4's Today programme, Ms Hernandez said: “If you can imagine that you lost a family member in the street, unexpectedly in such a horrific way, we really do need to manage what’s going on in terms of lives and loss.”

She declined to comment on the ages of those involved and whether police shot the suspect.

Ms Hernandez said: “One of the biggest things the police have been doing throughout the night is contacting the families of the victims this morning… making sure the families are first to know.”

She added: “It was a very contained incident. I think the sad thing for us is we have a community where many would have witnessed what occurred, right in front of their eyes, where they live. Absolutely devastated this morning.

“A lot of us are speechless.”

Plymouth Argyle have cancelled a pre-game press conference out of respect to the victims of the shootings in Keyham.

The press conference was due to go ahead on Friday morning ahead of the side's clash with Gillingham in League One on Saturday.

Earlier the club tweeted: "Our hearts go out to the victims of tonight's tragic incident."
