Police are appealing for information and witnesses following a violent assault that left a man blind in one eye.
The victim, 37-year-old victim Ali Doostizadeh, of New Southgate, had gone to Alexandra Palace with friends on New Year's Eve and was enjoying the view from the South Terrace. They were standing close to the fixed viewing binoculars outside the ice rink when a fight started nearby.
At approximately 01:30hrs on Sunday, 1 January, the victim attempted to break up the fight and was struck in the face with a bottle, causing a laceration to his right eye. He was taken to an east London hospital by a family member and is continuing to receive medical treatment.
Detectives would like to speak with anyone who was in the area at the time of the assault.
As it was New Year's Eve, officers believe that a number of people will have taken photographs and it is possible that they may have captured an image of the suspect.
The suspect is described as Asian, aged in his late teens, 5ft 10ins tall with dark brown hair. He was wearing an orange and white striped coat.
Detective Constable Ian Cant, from Haringey CID, said: "This was a particularly nasty and unprovoked attack on a young man who was celebrating the New Year with friends. The level of violence used has left him blind in one eye, and he remains in hospital recovering from his injuries.
"The suspect was wearing a very distinctive coat and I would ask anyone who was at Alexandra Palace, and who he took photographs to check the images to see whether he is in the background.
"Any piece of information may help to identify the suspect so that we can speak with him."
Anyone with information or who witnessed the assault is asked to contact police via 101 or @MetCC.
Alternatively, they can call Crimestoppers anonymously on 0800 555 111.
