Heartbreaking footage has emerged of an innocent dog walker days before he was allegedly stabbed to death by an Afghan migrant.
Wayne Broadhurst, 49, tragically died during the attack which also left a father and son injured on Midhurst Gardens, Uxbridge, in west London, at around 5pm on Monday.
Ring doorbell footage shows Mr Broadhurst doing his usual dog walk just two days before a knifeman is said to have launched a frenzied attack on him.
Shahzad Farrukh, 45, who is currently in hospital being treated for serious knife wounds has told his family that the assailant exploded in 'rage and violence' for no explicable reason.
His 14-year-old son was also taken to hospital with knife wounds following the attack.
A 22-year-old Afghan national - who arrived in the UK in a lorry five years ago - was Tasered and arrested at the scene. He is being held on suspicion of murder and attempted murder, the Met Police said.
Mr Farrukh's brother Umer told The Daily Mail: 'The Afghan man was staying with my brother. There was no argument or any other issue that led to the attack. He just went berserk and started attacking my brother and nephew in the house.
'I have been to see my brother in hospital. He's in a stable condition and can speak. He told me that they were all in the house together and then the Afghan man burst into a room with a knife screaming and went mental.'
He added: 'They ran out of the house and the Afghan man chased them. That's when he came across the dog walker.
'As a family we are very traumatised and our hearts go out to the family of the man who died. My brother is still trying to make sense of it all because there is no reason why this man attacked them. They knew each other quite well, none of this makes sense.'
Umer revealed that his brother works as a business consultant and bought the property on Midhurst Avenue last year for just over £500,000.
He added: 'We've been told by the police not to reveal too many details or the identity of the Afghan man. But he's known to us and was staying with my brother. I can't say more than that.'
Umer said that his family are of Pakistani origin and insisted that Mr Broadhurst's killing was not about race.
He added: 'This was a senseless, tragic incident and we are heartbroken. We are suffering as a family and so is the family of Mr Broadhurst.
'My brother is lucky to be alive, and should be home soon but we also feel the pain of Mr Broadhurst's family.'
Last night, it emerged the man suspected of killing him is an Afghan national who arrived in the UK in a lorry five years ago.
Home Office officials confirmed that the suspect arrived in Britain illegally in 2020 and was granted leave to remain around two years later.
The incident is not being treated as terrorism, but Metropolitan Police detectives are working to uncover any relationship between the suspect and the three victims.
According to residents, a fight had broken out involving the Afghan, who was living as a lodger in the home of the 45-year-old.
The 22-year-old chased two victims out the house, eyewitnesses said, before the dog walker was slashed across the neck.
The 14-year-old victim allegedly ran across the road and alerted locals to help save his father, 45, who suffered life-changing injuries, The Sun reported.
Footage posted online appears to show two police officers sprinting after the suspect, demanding that he drop the weapon and 'get on the floor'.
One of the officers raised his Taser and fired the 50,000-volt weapon before the suspect was seized.
There has been widespread shock within the local community following the brutal attack.
One witness told the Daily Mail: 'The Afghan man was chasing a man and a boy around the road and a local man who was with his dog tried to stop it.
'There was blood everywhere and the paramedics were there for at least 30 minutes trying to save his life. It was absolute carnage and very distressing to see.'
Another local added: 'The dead man is very well known around here. He's a lovely guy, very gentle and peaceful.'
A neighbour said the man who died was a binman who was 'just doing the normal dog walk that he does every day' and that he is 'the last person on Earth that you would think somebody would go for'.
The woman, who had taken over some flowers for the victim's wife, and added: 'I still can't get over it. If he was five or 10 minutes later taking the dog out would the same thing have happened?'
Another witness said: 'I saw a young man come running out of the house waving a large knife around. He had a mad look in his eyes and was screaming.'
A Home Office official confirmed the Afghan is not a resident of an asylum hotel or any other Home Office accommodation.
A spokesperson said: 'Our thoughts are with the family and friends of those impacted by this horrific incident.
'We are receiving regular updates from the Metropolitan Police. The priority must now be for the police to investigate so those responsible can be brought to justice.'
Chief Superintendent Jill Horsfall from the Met Police confirmed that the 'suspect lived in a private address'.
Robin Stevens, 50, who lives on the other side of Midhurst Gardens, said he heard a lot of sirens at about 5pm on Monday.
He said: 'We didn't really see anything apart from we heard a lot of sirens and were wondering where they were coming from. I left home at about 5.30pm, jumped in the car and as I've driven down it was all cordoned off.
'The tent was there. I must've counted about six squad cars that side, six or seven this side as well. It was quite shocking.
'It's a bit worrying really. I finished work at 10pm came back home about 10.30pm and I was talking to a couple of the coppers, all they could tell us was there had been a violent incident.'
He said he found out what happened on Tuesday morning and was 'shocked', adding: 'I grew up on this street, I've lived on this street for 50 years and I've always known it to be quite a family orientated area.'
Wisam Salah, 18, lives near the cordon and told how 'everyone is really panicked' after the incident in Uxbridge.
He said: 'Yesterday I was out, I came home about 7pm.When I came home I saw multiple police cars, I think more than five. I was extremely confused.'
Mr Salah added he was 'extremely shocked' when he found out what had happened, and that 'everyone is really panicked'.
One local claimed the Afghan had been living as a lodger for the past six months in the 45-year-old man's house.
A police tent could be seen at one end of the road with forensics working on the street earlier this afternoon.
Forensic officers were spotted walking down Midhurst Gardens towards the police cordon in a line. The 13 officers walked slowly and checked hedges on the sides of the road.
Four bunches of flowers were placed near the police cordon, while another was left by a local woman from a neighbouring road.
One woman who came to lay flowers near the police cordon on Midhurst Gardens said the incident made her feel 'absolutely sick'.
The woman, who wished to remain anonymous, said: 'Last night the police came down my road, it was about 5pm, I thought to myself 'oh my god I wonder what's happened'.'
'I just thought I'd come down and put some flowers down for the family.'
Chief Supt Horsfall said: 'This was a shocking and senseless act of violence that has left one man dead and two others injured.
'Our thoughts are with the victim's family and friends at this unimaginably difficult time.
'The incident will have understandably caused concern to the local community. I have deployed multiple officers to the local area, they will be here throughout the week to provide reassurance while detectives work intensely to piece together the circumstances.
