A manhunt is under way after a 15-year-old schoolgirl was punched in the face and racially abused at a train station in south London.
Officers received reports a suspect barged into a group of young women just before 7.45pm on February 6.
British Transport Police said when one girl challenged him outside Gipsy Hill station, he used racist words and punched her in the face three times.
Her friends attempted to stop him but he then assaulted them too.
Detectives released mobile phone images of a man they wish to speak to following the incident in Lambeth.
One photo shows him carrying a Sainsbury’s carrier bag and a laptop case.
He is seen wearing a dark jacket, blue shirt, blue jeans and a grey beanie hat.
Helen Hayes, Labour MP for Dulwich and West Norwood and chairwoman of the education select committee, said: “I’m appalled to hear about a horrific attack outside Gipsy Hill station this evening.
“My thoughts are with the girls who were subjected to terrible violence.”
A force spokeswoman said: “Do you recognise this man?
