A man has been charged with GBH after a member of staff at a Harpenden events venue was stabbed - with police now trying to trace a third victim.

Detectives are hoping to find third man who may have received an injury following the incident at Hoo House in High Street during the early hours of Sunday (November 10).

Officers were called at around 1am to a report of a stabbing.

It appears that a man was prevented from going into a smoking area with a drink. The member of staff, who tried to restrain him, was stabbed with a kitchen knife. A second man was also stabbed.

It is believed that there was another man who is unidentified to police, who received injuries because of trying to assist with the altercation, and detectives are trying to trace him

Matthew Narroway, age 20 of Sherwoods Rise in Harpenden, was arrested at around 2.30am in Kirkwick Avenue.

He was later charged with two counts of grievous bodily harm and possession of a bladed article.

Narroway was remanded into police custody ahead of appearing at Hatfield Magistrates' Court on Monday (November 11), where he was remanded in custody.

He is due to appear at St Albans Crown Court on December 10.

Detective Sergeant Paul Wadsworth said: “We are trying to trace a third victim who we believe was also injured during the altercation on Sunday morning, due to trying to help resolve the situation.

“This was an unusual serious, seemingly unprovoked, but targeted assault on three men. The first man suffered serious injuries, which could have been life threatening.

“I am asking firstly the third victim, a man, who remains unidentified at this time to contact police in order to assist us with our ongoing enquiries.

"We have a zero tolerance to knife crime in the district and officers quickly responded.

“We are also appealing to anyone who was inside the venue at the time of the incident or was in the area of High Street to contact us.

“And we are interested in hearing from businesses in High Street who may have CCTV footage which could be obtained to assist with our investigation.”
