One man has been killed, seven other people have been injured, two of them - a man and a woman - seriously.

West Midlands Police are hunting one man in connection with the stabbings at four locations across Birmingham city centre.

Emergency services were first called to Constitution Hill at 00:30 BST, before the attacker moved south.

The stabbings did not appear terrorism related, gang related or connected to disorder, police said, but they are treating them as linked.

No arrests have been made at this stage and anyone in the area at the time of the stabbings is asked to contact police and share any pictures they may have.

Police believe victims were chosen at random and there is no suggestion the attacks are terror related.

Armed police remain on the streets of Birmingham this evening to try to reassure the public, as an attacker who stabbed several people, killing one of them, remains at large.

One man was killed and seven other people wounded in two hours in the city centre during the early hours.

Officers remain at a number of scenes around the city centre, as well as on high-visibility patrol, said West Midlands Police.

A woman has described how she and a friend helped one of the Birmingham stabbing victims who she said was bleeding heavily.

Nikita Denton, 29, from Edgbaston said she had been celebrating her birthday in Hurst Street when a man shouted someone had been stabbed.

She and her friend ran towards the wounded woman, she said.

"My best friend Jay held her head and talked her through everything the whole time and wouldn't leave her side."

Scenes in the area were "frantic", she said, but she and her friend remained calm throughout.

"When the paramedics arrived they asked us to help," she added.

"I got water and used the torch on my phone to help them see the wounds as they didn't have a torch at that time."

"I'd hate to think if we weren't there that night as she would have been alone."

Business owners in the area of Birmingham affected by last night's stabbings are "just in shock".

Julia Robinson, from the Southside Business Improvement District, said businesses had worked through the night to provide police with CCTV footage from the area.

She also said paramedics taking part in a "safe space" initiative were on hand to help.

"Generally these paramedics are helping people [offering] drinking water and who might feel a bit sick, but last night they really came into their own and were able to deal really quickly with this incident and hopefully prevent any further loss of life."

Birmingham Ladywood MP Shabana Mahmood has said she has had concerns about police resources in the city centre, especially as more businesses opened up after lockdown.

"I know that the pandemic has increased pressures and we are one of the youngest cities - if not the youngest in city - in Europe and my constituency is home to a very large proportion of young people and many people who want to go out and enjoy themselves come to the city centre so there are challenges," she said.

"The lockdown and pandemic has heightened those challenges," she added, "so there is certainly a conversation to be had with government about the funding that they make available.

"There are those of us - myself included - who are concerned about the overall state of policing and who want to see the police have all the resources they need to keep all of us safe."

The Birmingham Ladywood consituency covers the city centre.

Forensic officers are still at the scene in Hurst Street - one of the scenes of the Birmingham stabbings.

David Nash, bar manager of the Village Inn on the street said emergency services had "acted very swiftly".

"They got the area closed down very quickly and reassured people very quickly."

"Unfortunately the world in which live at the moment, this could happen at any time and any place in any part of the country," he added.

Local restaurant owner Savvas Sfrantzis describes seeing a knifeman who carried out a sustained attack in Birmingham city centre.

Buses continue to be diverted away from affected areas in Birmingham city centre, disrupting services.

Parts of Hurst Street, Irving Street and Livery Street as well as Edmund Street remain closed after the stabbing incidents on Saturday night.

One man has died and seven people injured following a spate of stabbings. Here is what we know so far:

• Police receive reports of a stabbing in the north of Birmingham city centre, around Constitution Hill, at about 00:30 BST
• West Midlands Ambulance Service received an initial call to Colmore Row and Livery Street at around 00:40 before further calls over the next hour and a half.
• They were later called to Irving Street at 01:52 and to Hurst Street at 02:00, both in the south of the city centre.

• At each of those incidents, a number of stabbings took place, Ch Supt Steve Graham said.

• A total of seven patients were treated - five were taken to the major trauma centre at Queen Elizabeth Hospital Birmingham. An eighth did not require hospital treatment.
• Three of the five taken to the major trauma centre had critical injuries and one man was pronounced dead shortly after arrival.
• Police are searching for a lone suspect as part of a murder investigation.
• No arrests have been made at this stage.
• The victims appear to have been chosen at random.

It's going to be hard for officers to find a motivation for last night's attacks until the suspect has been arrested, BBC reporter Phil Mackie said.

"This man was walking through the city centre last night, apparently able to carry out a number of stabbings over a period of an hour and a half and still get away from each incident and not be captured by the police," he said.

"This is an active investigation and the key thing at the moment for West Midlands Police is to track that man down.

"They've said they have got a lot of images from last night, a lot of CCTV, and also there is some eyewitness footage as well which they're storing which suggests they've got a sense of who they're looking for - and if they need the help of the public and the media I'm sure they will release a picture.

"But at the moment that's not happened so that would suggest they've got a sense of who they're looking for."

Savvas Sfrantzis says he saw a woman being stabbed on Hurst Street. "I heard a scream," he said.

He said everybody thought the attacker was trying to take her necklace.

He said the attacker did not appear to be "panicked".

In large parts of Birmingham, it would be easy not to realise such awful events took place just a few hours ago.

A long stretch of Hurst Street in the city’s Gay Village remains cordoned off, while about a mile away at Snow Hill, just yards from police headquarters, there are forensic tents in the road.

You can’t help but notice the huge police presence, an effort to reassure people as the hunt for the attacker continues.

The leader of the opposition Sir Keir Starmer has tweeted his thanks to the emergency services for their work.

"All our thoughts are with the victims and anyone else affected," the Labour leader said.

Elsewhere in the city an event is taking place at Victoria Square.

Protesters have gathered talking about vaccines, saying it is poison.

Despite the incidents overnight, some parts of Birmingham are operating as usual.

The stabbings in Birmingham have left the "city, the region and the country in shock," said the West Midlands Police and Crime Commissioner. , external

Officers are following a number of lines of inquiry and have increased the uniformed and armed response in the city, David Jamieson said.

There is a high police presence at a number of scenes across the city, including Livery Street, Irving Street and Hurst Street.

“I have every faith in West Midlands Police who are working extremely quickly on this investigation," he added.

The area where some of the attacks took place is known as Birmingham's Gay Village.

It's a collection of bars and restaurants surrounding an open paved area that is bang in the middle of the Gay Quarter and China Town, so as well as bars there’s a Chinese supermarket and restaurants.

Just off Hurst Street is the main thoroughfare which is pedestrianised.

In recent weeks businesses have been working on the areas outside the bars to allow for social distancing The area has been working to improve its offerings to keep customers Covid safe and really making an effort to attract people back to the area.

Earlier, the attacker had made his way from Constitution Hill, a major route into the city and home to many bars, restaurants and hotels and onto Livery Street - a street which is bordered by Birmingham's Snow Hill station on the one side and car parks on the other.

A dedicated web page where witnesses can share information about last night's attacks has been set up.

West Midlands Police said it was working through witness statements to get a clear description of the attacker.
