The attack happened on Wednesday, 18 October, at an address in Islington, north London.

A man in his 50s was violently assaulted by Alex Ogden, 28, and was admitted to hospital for treatment, police said.

Due to comments made during the attack, officers said the incident is being investigated as a homophobic hate crime.

Detective Constable Lauren Gresty from the Central North Public Protection Unit has urged the public to assist police in locating Ogden.

She said: "Ogden is a dangerous individual and it is crucial that he is located as a matter of urgency.

"He is wanted for a number of offences involving violence and theft, and has a history of violent offending.

"Ogden maybe in possession of a knife, and it is vital the members of the public do not approach him. If you see Ogden, or know where he is, it is imperative that you call 999 immediately."

Ogden has been described by officers as a stocky, white male with a topknot haircut that is often braided into smaller plaits or worn long with the sides of his head shaved.

He has a Yorkshire accent, is known to travel around the country and has links to London, York and Sheffield.

The 28-year-old is also wanted after he failed to attend court on 31 August after being charged with three common assaults at York railway station.
