CCTV still have been issued by the Metropolitan Police showing two teenage girls, seen in the area where Ian Baynham, 62, suffered fatal head injuries.

The two girls are described as white, approximately 5ft 9in and 5ft 5in tall, with blonde hair. They were wearing jeans and one was wearing a black jacket over a green top. The male suspect is described as dark skinned, around 5ft 8in tall, of thin build and with black hair. He was wearing a black jacket.

Baynham was punched and kicked to death while on a night out celebrating his new job at the Home Office. He suffered fatal head injuries in the 'vicious' assault by three young people, two blonde girls and a boy, outside the South African High Commission.

Detective Chief Inspector Clive Heys, who is leading the hunt for the killers, said, 'I don't criticise Mr Baynham for his actions. If you are 62 years of age and minding your own business when somebody hurls abuse at you, I think you are entitled to remonstrate with them. It is horrendous that this can happen in Trafalgar Square on a Friday night'. 

Anyone with information, or who recognises the two young women in the CCTV images, should call 0207 321 9314 or Crimestoppers on 0800 555 111.
