Captured on camera: Leeds fans in the frame after cup final attack

The 42-year-old victim was head butted after the final, which Leeds Rhinos lost 6-30 to Warrinigton Wolves on August 28.

He was attacked as he travelled home with his wife and friend on a Metropolitan tran line between Wembley Park and Finchley Road tube stations at 6.40pm. He was taken to hospital to treat a large gash to his lip which needed thirty stitches.

His attacker got off the train at the Finchley Road station.

British Transport Police want to identify one man described as being white, possibly in his late 20s and about 5ft 9in tall with a shaven head. He was wearing a black hooded top and is thought to be from the Leeds area.

Detectives have also released images of six other men they wish to identify and trace. They are also thought to be from Leeds - possibly Cross Gates - who could have information about the incident which may help the investigation.

Investigating officer Det Con Eloise Lock said:"This was a particularly vicious attack on a man who was making his way home after going to see the match at Wembley.The victim suffered a serious injury to his lip which needed thirty stitches.
