TEENAGER Russell Allsopp sobbed as he told a court how he saw his brother bleed to death during an alleged road rage attack.

The 18-year-old told the Old Bailey on Monday that he saw blood gushing from Gary Allsopp's neck after accountant Abdul Janjirker lunged at him with a knife, stabbing him in the neck.

The jury was told Gary, 17, lost a 'catastrophic' amount of blood and died shortly after the stabbing, on April 23, 1999.

Father-of-three Janjirker, 50, of Healey Avenue, High Wycombe, denies the manslaughter of Gary, who lived in Southall.

He claims he was acting as an automaton or human robot after being hit on the head with a brick and losing consciousness in the midst of a barrage of racial abuse.

The court heard the Allsopps were in a Ford Escort driven by friend Carl Woodbridge when there was a minor traffic incident involving Janjirker's red Citroen Xantia in Lady Margaret Road, Greenford.

Unemployed Russell Allsopp said his brother got out of the car at the lights to check how busy traffic was on the road and then noticed him talking to a man when an argument erupted.

He said: 'I could vaguely hear them arguing above the music in my car. I heard Gary shout 'He's got a f***ing knife'

'I couldn't see one. I got two bricks from a garden when I heard him say he Janjirker had a knife. My natural instinct was to help protect my brother.'

He said he threw a half-brick to his brother and the other at Janjirker's car.

He continued: 'Then I saw him (Janjirker) make a lunge at Gary's neck. I couldn't see what he had in his fist. Gary's neck immediately started gushing blood.

'It was coming out of his neck like a tap.'

He added, sobbing: 'He shouted that he was bleeding to death but there was nothing I could do.'

Mr Allsopp covered his brother with his coat. The trial continues.
