A two-year-old boy has had his collarbone broken in a racially motivated attack at a London train station.
Police are appealing for information after the "unspeakable" attack at Highams Park train station on Sunday in which his mother was assaulted and dragged to the ground along with the pushchair.
She was attacked for having a mixed-race baby, police said.
Police have released CCTV of a man they want to speak to
Detective Constable Gerry Hughes, the investigating officer, explained: “The victim, who had her two-year-old son in a pushchair, was approached by a man at Walthamstow Central station.
“They both boarded the 2.47pm Liverpool Street to Chingford service as the train arrived at Walthamstow Central around 3.03pm. During the journey, the man began to racially abuse the victim.
“When the train arrived at Highams Park station, the victim left the train with her pushchair. She was assaulted by the man, who pulled her hair and dragged her to the ground along with the pushchair. The man then made off from the scene.”
Detectives have seized images of a man they believe has key information.
DC Hughes added: “This was an unspeakable attack on a mother and son, and we are determined to find the man responsible. I’d urge anyone who has any information into the incident, or recognises the man pictured, to come forward and assist officers in this investigation.”
