Officers investigating a robbery in Cuffley are appealing for information and witnesses.
At around 11.30pm on Wednesday (February 1), a man aged in his 20s was approached by three men in Tolmers Road.
They threatened the victim and stole his wallet and Rolex Skydweller watch.
The offenders are described as black men. One of them had a London accent, while another was wearing a black puffa jacket. They were all wearing dark clothing.
Detective Constable Ian Aldridge, who is investigating, said: “Thankfully the victim was not injured during what would have been a frightening ordeal for him.
“Enquiries are on-going to identify those responsible for this robbery and in the meantime local patrols are being increased in the area.
“I am appealing for anyone who was in the area around the time stated and believes they saw three men matching the description to get in touch.
“I’d also like to speak to anyone who believes they have been offered the stolen Rolex Skydweller watch for sale.”
