A bouncer accused of killing a Chiswick drinker with a single punch after reacting in a "flash of anger and frustration" during a row has been acquitted.

Kevin Griffith, 30, walked free from court after being cleared by an Old Bailey jury of being responsible for the death of Nicholas Adam Padget last July.

After protesting he was acting in self-defence, Griffith was cleared by the jury of his manslaughter.

As the verdict was read out on Friday, after more than seven hours of deliberations, Mr Padget's family looked on in silence.

During the trial, the court had heard Mr Griffith punched the 27-year-old at O'Neill's bar in Ealing Broadway, causing him to fall over and hit his head.

Dramatic pictures taken from the pub's closed circuit cameras were shown the moment he was felled, causing him to "crumple over".

But Mr Griffith, whose first night it was on the door, testified Mr Padget started the row after becoming abusive and aggressive before landing the first blow that was "hard enough to knock me off balance".

Mr Padget, who was two to three times over the legal drink drive limit, had earlier refused to leave, prosecutor Sarah Whitehouse told the court.

The pair got into a row, prompting Mr Griffith to hit Mr Padget, 27, of Heathfield Court, Chiswick, in the face.

The prosecutor said it was an over reaction from the bouncer of eight years.

"The prosecution case is that Nick Padget, being struck as he was, posed no threat to the defendant - he was too drunk," Ms Whitehouse told the court.

"At 5ft 8 he posed no threat to this defendant, who was 6ft 2, sober and a trained doorman.

"Whatever Nick Padget did.... there was no need at all for this defendant to respond in self-defence like he did. He reacted in a flash of anger and frustration."

She added: "What we do say when Mr Griffith struck out with that punch is that he did it in anger, not self-defence."

But in his defence, Griffith said: "I was fearful, I had just been hit. He clearly attacked me and my first reaction was to defend myself. I was shocked he was on the floor because I didn't think I hit him that hard."

He said he did not call police because he didn't want Mr Padget arrested for assault.

Griffiths, of Colliers Wood, London, denied manslaughter.
