The family of a man left in a coma after an attack have made an emotional appeal for help.
Omen Mugaviri, 38, was found severely injured by police officers in Pellat Grove N22 on Monday June 30 at around 1am.
He was immediately taken to hospital, where bleeding on his brain was found. Doctors were forced to remove a piece of his skull.
Police believe that Mr Mugaviri had been in the company of a group of people in the High Road N22 area earlier in the evening.
His aunt, Priscilla Nyana said: "My family is absolutely devastated by what happened that night and these last few months have been extremely difficult for us.
"Omen is a good man, and does not deserve what happened to him. I urge anyone who witnessed this or knows anything to come forward and help police with their investigation"
A 43-year-old man has been arrested and bailed until a later date in October pending further enquiries.
Police are now releasing a photo of a potential witness they would like to speak to in connection with this incident. She is believed to be 35 to 45 year-old white woman with dark brown hair and a sling on her left arm.
Detective Chief Inspector Paul Trevers from Wood Green Police Station said: "Due to Omen's condition we are unable to fully establish what happened between the eve of Sunday to the time he was found by police.
“If you are the person on the photo or know who she may be, please contact us so we can establish exactly what happened that night and arrest those responsible".
Anyone with any information is asked to contact Detective Sergeant Gordon Mckay from CID at Wood Green on 0203 276 3078.
