Residents of a "friendly" estate where a teenager's hand was chopped off in a horrifying machete attack say they have been left shaken by the gruesome crime.

Witnesses have been left traumatised and unable to sleep after seeing the 18-year-old man "writhing" in pain on the floor with his hand "cut clean off".

The victim was screaming for help and telling a growing crowd that he "was going to die" after he was attacked on the Swarcliffe Stanks estate, witnesses told LeedsLive.

They say the man was in good spirits and even made an x-rated joke as they used a belt to make a tourniquet around his arm to stem the flow of blood, and waited for police and paramedics to arrive on Tuesday night.

For some residents of the estate in Leeds, the attack did not come as a surprise.

One man said: "Obviously, I didn’t expect to hear that his hand has been chopped off - but I can’t say I’m surprised that something has happened.

"It is 100 per cent gang related, unfortunately.

"It’s a shame, this is a nice, friendly neighbourhood - we get along with a lot of people and everyone is nice to each other.

"But there are always issues with certain people. You just have to know what certain people are capable of, I guess."

Residents praised those who rushed in to help the bleeding victim.

A man said: "It was horrible - the poor lad was writhing in pain, as I am sure you can imagine.

"It didn't surprise me to see so many people try and help him - this is a good neighbourhood.

"But yeah, there are definitely certain people who it would be better for everyone if they were gone."

A woman, who lives close to the scene of the attack, said the gruesome incident left her traumatised and unable to sleep.

She said: "I have not been able to sleep - it was awful. He shouted for help, he said he was going to die.

"We came out to help him and others did too - people were doing what they could to help the poor lad.

“His hand was cleanly cut off by a huge machete - it was like a clean cut.

"It's something that you don't just forget. It was proper horrible."

Victoria, another resident, compared the bloody scene to a Hollywood horror film.

"His hand was on the road. I have never seen anything like it, it was like something off of a horror film. I hope he’s doing okay.”

The victim was rushed to hospital, where it is understood that surgeons were able to successfully reattach his hand.

Detective Inspector Guy Shackleton, of Leeds District CID, said: "We are treating this incident very seriously and are carrying out a detailed and comprehensive investigation to establish the full circumstances and identify those responsible.

“The victim has suffered an extremely serious injury and is currently receiving treatment in hospital.
