Scotland Yard has appealed for information from members of the public on the Sunday night assault on Lt Gen KS Brar and described the four assailants as wearing dark clothing, long black jackets and having "long beards".

Stating that detectives were keeping an open mind on the motivation behind the attack, the police said in a statement Monday that they were particularly keen to speak to people who assisted Brar and his wife after the attack on Old Quebec Street in central London.
