A vigilante gang leader who battered a Hayes teenager to death for spitting at his elderly father was jailed for at least 20 years today (Thur).

Myles Cadogan, 24, and his friends - including a professional boxer from Eastcote - hunted down 19 year-old Fuad Buraleh, of Clayton Road, Hayes, less than half an hour after the incident on a bus.

The Somalian refugee was punched, kicked and bludgeoned with a bottle until his face was 'caved in' by the force of the blows.

Myles' 67 year-old father Carl, who had summoned his son to 'sort it out', watched the gang chase the victim to his death before calmly getting a bus home.

Judge Timothy Pontius sentenced Myles Cadogan, of Brondesbury, to life imprisonment for murder and told him he must serve at least 20 years behind bars before being considered for parole.

Carl Cadogan, of Hanwell, was jailed for 18 months for violent disorder and gang members Scott Baker, 22, of Long Drive, South Ruislip, Lee Beavis, 26, of Windermere Avenue, Eastcote, Anthony Sheehan, 22, of Northolt, and Richard O'Donoghue, 24, of Hanwell, were all jailed for two years for the same offence.

Judge Pontius told them: "I am in no doubt at all that Fuad Buraleh and his cousin behaved disgracefully on that bus.

"But the call you, Carl Cadogan, made to your son was intended to be and was received as a call to arms so that those two young Somalians could be found and punished for their misbehaviour.

"Nothing they had done could possible come anywhere near the retribution which was carried out and which ultimately resulted in the death of a young 19 year-old, leaving a family who are struggling to accept it happened in this country to which they had come as refugees from war ravaged Somalia."

Beavis, who is an amateur English boxing champion and undefeated professional featherweight, and Sheehan have already spent more than seven months on remand.

Baker was on licence after being released early from a two year sentence for possession of cocaine with intent.

Sheehan was also in breach of a 12 month conditional discharge for possession of cocaine dating from August 2007.

O'Donoghue has a previous conviction for robbery, Myles Cadogan for possession of a prohibited weapon, Carl Cadogan for common assault in 1997, and Beavis for racially aggravated threatening behaviour in May 2002.
