Judge John Devaux was unharmed in the attack at Ipswich Crown Court yesterday - despite reports that his robes and wig were pulled off – and returned to the court moments later, according to the Daily Mirror.
The attacker is being held in custody after Suffolk police were called to the court.
A jury had earlier found Philip Graham, 30, of causing the death by dangerous driving of Derek Foster. But when Judge Devaux delivered his sentence, Mr Graham’s brother Paul removed his top and started ‘battering the hell’ out of the judge, according to a witness.
The BBC reports that on his return the judge told the court: ‘It's an incident which does not occur every day.’
Paul Graham is expected to reappear before the court today.
