Muggers attacked a man and threatened him with a knife on election night.

Two men went up to the victim, asked for his mobile phone and chased after him when he fled in Banstead between 10.20pm and 10.35pm.

After attacking him and threatening him with a knife, the muggers ran up a stairwell in parade of shops in Bolters Lane. The men were about 19 or 20 years old and wore grey hoodies.

One attacker was slim, black and about 6ft. The other man was a bit stocky, white and about 5ft 7.

Detective Constable James Vernon said: "This was a very traumatic experience for the victim which has understandably left him very shaken.

"We are especially keen to speak to anyone who was in the area at the time of the incident as they may hold vital information and possibly have witnessed events surrounding the assault.

"We are also keen to hear from anyone who may have seen anyone matching the description of the two men to contact police on 101 - any information could prove vital in bringing those responsible to justice."
