A Crystal Palace fan was photographed as he lay dying after being knocked out in a fight with a train passenger, an inquest heard.

Dad Richard Powell, 39, from Higham, who ran a plastering firm and featured on the BBC series DIY SOS, was floored when he got involved in a scuffle on Victoria station's concourse.

Immediately after the 29-second fight, Denis Busu stood over him and took a picture of Mr Powell to send to his girlfriend while allegedly said "serves him right," Westminster Coroner's Court heard.

Mr Busu admitted he had taken the picture as he uses smartphones everyday but thought Mr Powell "was having a seizure".

He denied he said Mr Powell deserved it and had actually said: "Look at you, you're drunk."

Mr Powell and his brother-in-law Ian Wilmore had been heading home from a friendly between Fulham and Crystal Palace when they got off a train and stepped on Mr Busu's shoe, causing it to come off.

But rather than apologise, an argument erupted and punches were thrown.

Mr Powell died in hospital from bleeding on the brain three days later in August last year.

The inquest heard the pair had downed six or seven pints of beer and three shorts before, during, and after the match and were heavily intoxicated.

Mr Busu, 21, was initially arrested on suspicion of causing grievous bodily harm and released on bail but the prosecution dropped the case.

Describing how the fight developed, Mr Busu told the inquest he had been heading to his girlfriend's house for a family barbecue when he got off at Victoria.

He said: "I had my earphones in and I was walking towards the platforms when I felt someone step on my shoe.

"I thought, these guys are going to try and assault me or whatever, so I stepped back. He tried to punch me, but he missed. I did punch both of them once" - Denis Busu

"My shoe actually came off, so I turned around, which is a normal reaction, and said 'what the ****, man'.

"One of the men looked at me with a kind of screw-faced expression. Straight away, I realised they were clearly extremely drunk.

"One of them got in my face really close and grabbed me around my chest. He was very aggressive.

"I thought, these guys are going to try and assault me or whatever, so I stepped back.

"He tried to punch me, but he missed. I did punch both of them once.

"Then one of them got up, and the other one held him back - but he just seemed to fall on the floor. It did seem like a seizure.

"He was shaking, almost snoring, and couldn't really breathe.

"I didn't know what to do so I just left. There were people helping.

"I use technology for everything, and I wanted to show my girlfriend, 'look, these two guys just attacked me', so I took a picture.

"I didn't say 'that serves you right'. I said 'look at you, you're drunk'."

Juanita Cox, who saw the fight, said: "Mr Busu simply wanted Mr Powell to leave him alone" and that the pair "came across as extremely aggressive".

Detective Sergeant Andrew Natrass from British Transport Police talked the inquest through a series of still images from CCTV cameras which showed the 29-second scrap between the three men.

He said: "One of the men actually clipped the heel of Mr Busu's shoe.

"He turned around, expecting an apology - but he didn't get one. It just escalated very quickly from there.

"You can see that Mr Wilmore clearly takes offence at whatever Mr Busu says, and he stops in front of him, squaring up to him.

"The CCTV shows them standing nose to nose."

DS Natrass said Mr Wilmore can be seen "punching or pushing" Mr Busu away, before Mr Powell gets involved.

Mr Wilmore is floored in the scuffle, and Mr Busu and Mr Powell exchange punches, before Mr Powell also falls down.

DS Natrass said: "When Mr Powell gets back to his feet, Mr Wilmore can clearly see that things are getting out of hand, and tries to restrain him.

"But Mr Powell just collapses on the floor."

Pathologist Dr Simon Poole, who carried out the post-mortem examination, said: "The punch caused significant damage to the right vertebral artery and led to bleeding in the brain."

He gave the cause of death as "traumatic sub-arachnoid haemorrhage".

Coroner Dr Shirley Radcliffe recorded a verdict of lawful killing.

She said: "When a blow is landed and causes the death of an individual, we have to understand whether this was a lawful, or unlawful killing."

She continued: "Mr Busu had no intention whatsoever of taking Mr Powell's life.

"He was simply defending himself against two men who were being particularly aggressive.

"He planted a punch in self-defence that has led to Mr Powell's death and so I have to record a conclusion of lawful killing."

In March, the Crown Prosecution Service confirmed no one would face charges in connection with Mr Powell's death.
