Police believe the fatal shooting of a man on his own doorstep was a "case of mistaken identity".

Detectives are now appealing for witnesses and any information about the killing in Wiltshire Gardens on Monday night (May 18).

A man, who officers believe was a 27-year-old, was found suffering a gunshot wound to his head. He was pronounced dead at the scene.

Detectives said they believe he was killed in a case of mistaken identity.

It is believed he opened his door to two suspects who were wearing dark clothing and motorcycle helmets.

They left the scene on a moped, heading towards Finsbury Park Avenue.

A post-mortem examination is scheduled to take place at Haringey Mortuary tomorrow (Thursday May 21).

His next of kin has been informed and are being supported by specialist officers.

Police are still waiting for a formal identification.

Detective Chief Inspector Andy Partridge said: "This was a cowardly attack on an innocent man who was shot dead on his own doorstep.

"Although at an early stage of the investigation, I strongly suspect that he was not the intended target of this attack, making this case all the more tragic.

"It would have still been light when the shooting took place and I'm hoping there are people out there who saw something who we've not yet spoken to."
