Police are on the hunt for two robbers who posed as police officers, held a man at gunpoint and then stole his Range Rover.

The victim, 60, was stopped in his luxury car in Bromley by what he believed was an unmarked police car when flashing blue lights indicated for him to pull over.

He had been driving along Upper Beulah Hill at around 8:40pm, Monday, February 17 when the two men pulled him over, introducing themselves as police officers.

The victim got out of the car after one of the suspects produced a false arrest warrant and asked him to go speak to his 'colleague' in their supposed police car.

When the 60-year-old approached their car, the man in the driver's seat pointed a firearm at him.

At this point, the first suspect drove off in the man's Range Rover, followed by the second vehicle, both heading towards Upper Beulah Hill.

Detective Constable Joanne Austin from the Met’s South Area Command Unit called it a "frightening experience for the victim" who had pulled over in good faith believing he was assisting police.

"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."

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

The victim also gave a 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.

This is currently being treated as an isolated incident, and police added that 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.
