Police investigating a stabbing that left the victim requiring extensive reconstructive surgery want to speak to a man from Hendon in connection with the incident.

Officers from the Met were called to a pub in Chiswick High Road in south west London at 11.20pm on Saturday February 19 following reports of a stabbing.

Emergency services attended and found a 40-year-old man who had serious injuries to his head, neck, arm and hand.

He was taken to hospital where he underwent surgery and his injuries will require ongoing treatment and rehabilitation.

Another man was also subjected to an assault by multiple people, leaving him with a broken nose, swelling and bruising.

The Met says its detectives have identified 30-year-old John Paul McDonagh and 19-year-old Shamus Mongan as people they wish to speak to about the incident.

McDonagh is from Greenford while Mongan is from Hendon. Both men are known to frequent other areas and could be anywhere in London, police say.

Detective Sergeant Luke Taylor said: "This was an unprovoked attack that left the victim with really serious injuries that will have a lasting impact. This sort of violence cannot be allowed to stand and we will do all we can to bring those responsible to justice.

"We have carried out a number of enquiries since the incident and have been able to identify two named individuals who we want to locate and speak to urgently. We have taken the decision to release their photos and their names in the hope that someone knows them, or knows where they are."

Anyone with information should call police on 101 or Tweet @MetCC with the reference 7914/19FEB.
