Police are appealing for information on a man who is suspected of assaulting a 15-year-old boy in a racially motivated attack - leaving him with a broken jaw.
The victim, who is black, was waiting at a bus stop when the suspect shouted racial abuse at him. The victim asked him to stop and walked off. He was then punched in the jaw which broke in two places.
Others at the bus stop tried to detain the suspect but he managed to get on board a 453 bus and left the scene prior to police arrival.
The victim was taken to St Thomas' Hospital and received surgery on his jaw, and will require further medical attention.
"This is a particularly vicious and unprovoked attack on a schoolboy by a fully grown man," says DC Barry Vinall, the officer in charge of the investigation.
"Not only did he suffer severe injuries he was subjected to terrible verbal abuse as well. We would appeal to anyone who might have seen the attack happen or might recognise him from your journey to work to contact us."
The suspect is described as a light skinned black man, approximately 40 years old with a bald head, about 5'9" tall. He was wearing a black suit with a white shirt. It is thought he might have been commuting to work and therefore might use the route on a regular basis.
The crime is being investigated by Southwark Police's Hate Crime Unit. It is considered a racially aggravated assault because of the racial nature of the insults used.
If anyone has any information they should contact contact DC Vinall at Southwark Hate Crime Unit 020 7232 26168 or Crimestoppers 0800 555 111.
