Police are on the hunt for two men who threatened a driver with a firearm before stealing his car in Bromley.

The 60-year-old victim came to a stop in his black Range Rover in Upper Beulah Hill at about 8.40pm yesterday when he mistakenly believed an unmarked police car on blue lights had indicated for him to pull over.

He got out of his car after one of the suspects introduced himself as a police officer and presented a false warrant card.

The suspect then requested that the victim speak with his phoney 'colleague' in their car. As the victim approached the vehicle, the man in the driver's seat pointed a gun at him.

It was then that the first suspect made off in the victim's Range Rover, with the second suspect following on.

Detective constable Joanne Austin from Metropolitan Police's south area command unit said: “This was a frightening experience for the victim, who pulled over in good faith believing he was assisting police.

“The suspect’s car is described as dark coloured, and is possibly a Vauxhall Astra.

“A blue flashing light was used to give the ‘police car’ an air of authenticity and the men confidently pretended to be police officers. This was a pre-planned and sinisterly well-executed offence and we need to locate these offenders as soon as possible.

“We have the description of one of the suspects, who is thought to be white, aged between 25 and 30 and around 5ft10ins to 5ft11ins tall. He is of slim build, clean shaven and was wearing a black hooded top, with the hood worn off his head. He also spoke with a local, south east London accent.”

Officers who make stops while not in uniform will make their identity clear. Anyone approached by a plain clothed police officer should feel comfortable speaking to them, and members of the public can always ask to check officers’ ID closely. They should have this on them at all times.

Anyone with information is asked to contact police on 101, quoting CAD7781/17Feb20 or stay anonymous by contacting the charity Crimestoppers: 0800 555 111/crimestoppers-uk.org
