Man 'racially attacked' at Tottenham Hale station
A father was kicked and punched to the ground in front of three young children in what police have described as an attack "driven by racial hatred".
British Transport Police (BTP) said the man, aged 28 and from eastern Europe, was at Tottenham Hale Tube station in north London when he was assaulted by four men on 26 February.
The group made racist comments towards the children, police said.
Investigating officer PC Craig Murray said the attack was despicable.
The victim was returning from a Russian festival with his three-year-old daughter and his partner along with a friend and their two children, when the men got on the train and started making racist comments.
Mr Murray, from BTP's Hate Crime Unit, said the victim was punched in the face and knocked to the ground before being further attacked by the group after he got off the train at Tottenham Hale.
A witness called police and a full search of the surrounding area was carried out, but the men had already left the area.
"This attack was despicable. Not only was it unprovoked and completely driven by racial hatred, but it was carried out by a group against a victim who could not have defended himself in front of three very young and vulnerable children," Mr Murray said.
"Both the Tube service and the platform at Tottenham Hale would have been busy at the time and I'm sure many people will have witnessed the attack or perhaps noticed this group of men fleeing the scene."
The man who officers believe to have been the main instigator is described as white, approximately 6ft 1in tall and of average build. He had a shaven head and stubble on his face and was wearing a green jumper, blue jeans and trainers.
The rest of the group are believed to have been wearing Arsenal football tops.
Officers would like anyone who witnessed the incident, which happened between 18:00 and 19:00 GMT, to come forward.
