A man was left with life-changing injuries to his neck and face following an attack in Rickmansworth.

Herts Police have this afternoon (December 21) appealed for witnesses after the “GBH-level assault” in Meadow Way at 1.45pm on Tuesday, December 12.

The victim suffered injuries consistent with being stabbed, a force spokesperson said.

Three Rivers Local Crime Unit have been following lines of enquiry – including house-to-house visits and CCTV reviews – and officers now want to trace the driver of a white Audi 4x4.

The car, believed to be a Q model, is thought to have travelled along the road between 1.30pm and 2pm on the day. Officers believe the driver could be a vital witness.

It is currently unclear whether the victim, a man in his 30s, knew the attacker. Police have been contacted for clarification. Updates to follow.

Detective Sergeant Darren Machin, who is leading the investigation, said they are still exploring “several avenues of enquiry”. He added: “We are very keen to trace the driver of this white Audi because we have reason to believe they may be a key witness, or have dashcam footage of the incident.

“I’d like to stress to the public that we are treating the driver as an innocent bystander in this incident and not a suspect, so please – if you think this could be you, a friend or family member, contact us without delay as you could provide us with key information.”

He also appealed to any motorists travelling along Meadow Way, Highfield Way, Berry Lane, Dog Kennel Lane and Nightingale Road between 1.30pm and 2pm to check their dashcam footage.
