Police have released an e-fit of a man they are hunting who is suspected of savagely attacking a Tottenham fan in an unprovoked assault.

Michael Voller, 23, who formerly worked for Spurs as a training-ground gardener, was punched in the face as he left Wembley Stadium following last month’s FA Cup semi-final.

Mr Voller was left with a broken cheekbone, eye socket and skull after the attack by a set of fellow Spurs fans, who may have mistaken him for a rival Chelsea supporter.

Although Mr Voller has been discharged from hospital, he still needs treatment and doctors are concerned that his eyesight may be permanently damaged.

According to the e-fit, the man they are hunting is white, has short brown hair, brown eyes and appears to be aged in his early twenties. The suspect is described as being approximately 5ft 10in. He was wearing a black hooded top or jacket.

The attack happened at around 7.30pm outside Moore Spice, an Indian restaurant on Engineers Way, close to Wembley Stadium.

Mr Voller, who had attended the match with a group of friends, was targeted by a group of Tottenham fans walking in the opposite direction.

Police believe one of the group thought Mr Voller was a Chelsea fan and punched him in the face.

Investigating officer, Detective Constable James Robb of Brent CID, said: ‘This was a violent and unprovoked assault that has left a young man with some terrible injuries that could end up affecting him for the rest of his life.

‘This kind of violence has absolutely no place at a football match, and I sincerely hope that those who were with the person responsible do the right thing by Michael, who is a fellow supporter and has supported Tottenham since he was a young boy.
