A thug who started a vicious brawl in Greenford which led to the death of his friend was jailed for 18 months for stashing a hammer in his trousers to use as a weapon.
Paul Killeen provoked a fight at the White Hart last summer which led to the death of Les Wilkinson under the wheels of a car, a judge said.
The 39-year-old was cleared of affray when a jury at Isleworth Crown Court failed to agree a verdict.
But Judge Sam Katkhuda, jailing him for having an offensive weapon in public, said Killeen started the brawl when he confronted two cousins on the night of June 13.
Killeen had drunk between 20 and 22 pints of strong lager before approaching Martin and Patrick McDonagh with the hammer down his trousers as the pair played pool.
Mr Wilkinson - also known as Les Mortimer - was also in the pub armed with a knife when an argument broke out.
When the row escalated outside, 19-year-old Martin McDonagh drove off in his Ford Mondeo along Greenford Road, hitting and killing 48-year-old Mr Wilkinson.
He was earlier found guilty of causing death by dangerous driving, but failed to appear for sentence on Friday. A warrant was issued for his arrest.
Patrick McDonagh, 23, of Kingston Road, Southall, also repeatedly drove a Vauxhall Vectra at Killeen and others outside the White Hart. He was found guilty of dangerous driving and was handed a 50 week suspended sentence and banned from driving for a year.
Responding to claims that Killeen felt threatened by the McDonaghs, Judge Katkhuda said: "But he started the whole thing. The McDonaghs were playing pool in the pub and nothing was going on. He visited them in that section of the pub and brought with him a gang to confront them. I heard all the evidence and that is how I see it".
The McDonaghs initially reused to fight but tempers flared on all sides after the men were asked to leave, added the judge.
He said: "Patrick McDonagh foolishly and stupidly drove his car on to the pavement and it was obvious he was trying to inflict injury on those on the pavement. He tried twice and you hit his car with the hammer.
"Martin McDonagh drove away in panic because at first he was chased by Mortimer with a knife. Afterwards, obviously in fear for his life, he drove away and unfortunately it resulted in the death of Mortimer who was run over on the ground."
Judge Katkhuda said there were three aggravating features to Killeen's part in the trouble - the amount of alcohol he had drunk, being armed with a hammer, and displaying hostility by calling a minority group "pikies".
