Nic Chuter lives on Mapperley Road, close to the junction of Woodborough Road in Nottingham, not far from where a man was found dead on Magdala Road.

He woke up to the sight of flashing lights from police cars outside his home, which is within the cordon.

The former emergency planner said he was greeted by armed police officers as he left the house.

"[The] first thing we saw this morning when I took the children to nursery was someone calling me over with a very large gun saying: 'Hello, what are you up to?'".

"We're not able to use the car as it's being counted as part of a crime scene, so everything within the cordon is staying put."

You may find some of the details in this post upsetting

An eyewitness has told how he witnessed a young man and young woman being stabbed on Ilkeston Road, close to the junction with Bright Street, at about 04:00.

The man, who asked to remain anonymous, said: “Being a hot night, I had the window open and I just heard some awful, blood-curdling screams.

"It’s often quite busy with people coming back from town and you get the usual boyfriend-girlfriend arguments, so I thought it was something like that.

"I looked out of the window and saw a black guy dressed all in black with a hood and rucksack grappling with some people. It was a girl, and a man or boy she was with - they looked quite young.

"She was screaming 'Help!' I just wish I'd shouted something out of the window to unnerve the assailant.

“I saw him stab the lad first and then the woman. It was repeated stabbing – four or five times. The lad collapsed in the middle of the road.

“The girl stumbled towards a house and didn’t move. The next minute she had disappeared down the side of a house, and that’s where they found her.

“I’d say it all happened within five or six minutes. The attacker then just walked off up Ilkeston Road towards town, as calm as anything.”

The man said he phoned 999 and police arrived at the scene within five minutes. He said paramedics spent about 40 minutes trying to revive the pair.

He said he had been too scared to intervene or leave his home following the incident.

“It was a horrific thing to witness. I’m in bits here,” he said.

One resident on Ilkeston Road has spoken about how police were "banging on my door" at around 05:00 this morning saying they needed CCTV footage.

The man, who gave his name as Wayne, said he was told the incident happened around 04:10 BST, before being asked if he had witnessed anything.

"I didn't see or hear anything, but I'm not surprised this sort of thing has happened around here," he said.

An eyewitness in Nottingham has been speaking to BBC News' Midlands correspondent Navtej Johal.

Lynn Haggitt says she saw a van hit two people in the city centre, though it wasn't immediately clear where this incident is thought to have occurred.

She says she saw the driver "look in his mirror" and see a police car behind him, at which point he "quickened up" before going "straight into" two people.

"The woman went on the kerb and the man went up in the air," Haggitt says, adding: "It was such a bang - I wish I never saw it - it’s really shaken me up."

Asked how she was feeling, the eyewitness said: "I’m shaky - I’ve never seen anything like it."

She added: "I went over. Perhaps I shouldn’t have gone over, but I wanted to see if I could help.

"The woman was sitting up on the kerb – she looked OK – the man was laying down but then he got up.

"But I just can’t believe he was able to get up."
