Police are hunting a suspect after a man was held at knifepoint and robbed in Rickmansworth.

Hertfordshire Constabulary said the 33-year-old victim was approached as he walked along Uxbridge Road at around 10.20pm on Tuesday July 1.

He was then threatened and led to Cedars Avenue where the attacker demanded he hand over any valuables.

After the victim gave his money he was led back to Uxbridge Road before the robber ran off down an underpass on Ebury Road.

The suspect is described as a white male of between 5ft 7ins and 5ft 8ins tall. He was of a medium build and wearing a white t-shirt, black woolly hat and a black scarf covering his face.

Detective Constable Paul Burton is investigating and said: "I would appeal to anyone who was in the area around these times and perhaps saw someone loitering or acting suspiciously matching the description of the suspect to contact me."
