A resident who did not wish to be named told the BBC: "I am really terrified. I don’t like these things happening. I think the situation is getting worse, I’m afraid.”

On what more needs to be done to stop incidents of this nature, they added: “I think education and I also think that maybe we need a stronger police force.”

The large cordon has meant many businesses in the busy town centre are unable to open today.

One of them, Cleo's Delicatessen, posted on Facebook: "Unfortunately, there was an accident near the AMP last night, so we can not get into either of the buildings. Business should be back to normal on Monday."

With investigation work continuing, Nottinghamshire Police is still keen to hear from anyone who saw what happened.

Det Ch Insp Ruby Burrow said: “We know five people were injured but we’d still like to hear from anyone else involved.

“Any witnesses who were in Arnold Market Place, or the wider town centre area around this time, should also get in touch.

“We'd appeal to anyone with relevant dashcam, CCTV, doorbell or mobile phone footage to speak to an officer."

Nottinghamshire Police said an altercation had taken place in the town centre a short while before the incident.

Det Ch Insp Ruby Barrow said: "Although there is no wider risk to the public, this was a serious incident which will have caused concern in the community.

“We believe an argument has taken place in Arnold town centre and this has resulted in a car being driven at a group of people."

We've just had a further update from Nottinghamshire Police.

The force said in addition to the man who suffered life-threatening injuries, four other men suffered less serious injuries.

It added counter-terrorism police were not involved in the investigation and officers were still working to track down an identified suspect, a white man.

Michael Payne, MP for Gedling, confirmed the incident was not suspected to be terror-related and added there was not currently any concern about a wider risk to the public.

Speaking to the BBC at the scene, he added: “We’re a tight-knit community in Arnold.

“This has been my home my entire life. I live in Arnold and we’ll respond in the usual way as a community and will support the police in the important work they’re doing.

“My best wishes go to the individuals who’ve been hurt in the incident and I seriously hope that the said individual who’s got life-threatening injuries makes a recovery. My thoughts are with them and their family.”

Payne attended the scene alongside Gedling Borough Council leader John Clarke.

Clarke has called for barriers along the road, adding that the borough council had called for the road to be blocked off to traffic.

He added: “There need to be barriers, there needs to be prevention, and we need to look at it seriously to make people feel safe, to make the businesses stay here so they’ll prosper.”

Carolynne Watson said she was "really shocked" when she visited Arnold on Saturday morning and saw the scene.

She added: "I really hope that everyone who has been injured is OK and my thoughts are with them. It’s really quite shocking."

Arnold is a town based in the Gedling borough of Nottinghamshire. It lies about three miles north of Nottingham city centre.

One of the most well-known landmarks in the area is the former Home Brewery building, in nearby Daybrook.

The brewery was founded in 1875 and the building, which dates from 1936 became famous for its gated frontage.

The town was also a centre for the knitting industry, and was the site for the first major documented incident of the Luddite movement in 1811, when a group of framework knitters destroyed stocking frames.

Here are a couple more photos showing the cordon in Arnold town centre.

A stream of shoppers were now being turned away from the cordon area, with police speaking to people at the scene.

There is an atmosphere of concern for those people who were injured, and an expectation that the town will be cordoned off for much of the day.

A spokesperson for Gedling Borough Council, which is headquartered in Arnold, said it was aware of the incident.

They added: "Our thoughts are with everyone affected.

"We are working closely with Nottinghamshire Police as inquiries continue.

"Police have confirmed there is currently no indication of any ongoing threat to the wider public. Please be advised to stay away from the area while police investigations continue."

Police said a red Vauxhall Astra crashed into a number of pedestrians in Nottinghamshire.

Images taken from the scene show a red car with significant damage to its bonnet.

The cordon stretches across Market Place, where police were called to in the early hours of Saturday.

Police at the scene told BBC News there was no indication to suggest the crash was terror-related.
