Police are hunting a conman who posed as a police officer to talk his way into an elderly man's home and steal almost £300.

Detectives have released an e-fit image of the suspect, who dressed in a police uniform to burgle the house in Sevenoaks.

The victim, aged in his 70s, says a man dressed as an officer knocked on his door in Church Field and claimed the victim had used forged bank notes in a local shop.

He said he was there to "seize" the notes and any others he had. He then went into the house and left with £280.

The suspect is described as being a slim, white man aged in his 50s, with black hair, glasses and approximately 5ft 7in tall.

Officers are now appealing for the public's help to identify the suspect, and are urging people to always ask callers to prove their identity.

PC Pat McCartan said: "If a police officer calls at your door he or she will be more than happy to provide proof of identification and will have no problem waiting while you verify who they are by calling the police control room.

"Fortunately in this case the victim was not harmed in any way, but we would very much like to speak to anyone who saw anything suspicious or who has any information that will help us identify the person responsible."

Anyone with information is asked to call PC McCartan on 01622 604225 or Crimestoppers anonymously on 0800 555 111, quoting crime reference YY/20507/14.
