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 second victim.

Detectives are hoping to find second man who may have received injuries 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.

It is believed that there was another man who was also stabbed, and detectives are trying to trace him. His first name is Nathaniel.

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 Inspector Adrian Lysak said: “We are trying to trace a second man called Nathaniel who we believe was injured on Sunday morning.

“This was an unusual, serious, seemingly unprovoked, but targeted assault on two men.

"The first man suffered serious injuries, which could have been life threatening. 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.”
