A conman posing as a policeman called DC Wally tried to trick someone out of £5,500.

Police are hunting for the fraudster who introduced himself as 'DC Wally from Hammersmith Robbery Squad' when he rang a man in Raynes Park and tried to persuade him to withdraw the cash for fingerprinting.

Police were called about the attempted fraud in Carlton Park Avenue, near Raynes Park Station on Wednesday.

MPS Merton tweeted: "Thankfully man receiving call not deceived. Treat any calls requesting cash with extreme caution. Not a request police would normally make."

No arrests have been made.

Wimbledon police are investigating.
