A man has lost one of his eyes after he was attacked with a glass bottle.

Metropolitan Police say they found a 20-year-old man suffering from serious facial injuries after being called to a pub in Great North Road, Barnet at 1.40am on Sunday March 1.

He had been struck with a glass bottle, police said.

The man was taken to hospital where he lost one of his eyes as a result of the assault. He also suffered a fractured eye socket and a broken nose.

Police believe the victim went to intervene when he saw the suspect punch another man in the face, knocking him out.

The force says the suspect then turned on the victim and became aggressive towards him, picking up a glass bottle and throwing it in his face.

The suspect is described as being in his mid-20s, with pale white skin.

He had a shaven head and wore a black lightweight coat.

Police say he was of a chubby build.

Detectives are investigating the incident.

Detective Constable Emma Thompson, of the North West Command Unit, said: "This young man has suffered a life-changing injury after he tried to act as a good Samaritan and intervene in another assault. As a result, he too was attacked and is now coming to terms with what his life will be like now.

Anyone who may have been present in the pub that night is urged to contact police on 101 quoting ref CAD 1158/01MAR20.
