Three groups of teenagers were threatened with knives during a Wimbledon robbery spree.

The first attack took place on Ridgway Place, near the junction with Ridgway, at 6.15pm Sunday.

Three black men in a white Volkswagen Polo, registration LD19 CXK, pulled up to two 16-year-old boys and threatened them.

The men intimated they had knives and made the boys hand over items of property.

Twenty minutes later another attack took place, this time along Grand Drive.

Two 17-year-old boys were walking when a white Volkswagen Polo carrying three black males pulled up beside them.

The victims were approached and one of them was forced to hand over his phone. Once again the offenders made it out it seem as though they had knives.

The final incident took place at 6.45pm when three black men robbed a 19-year-old after they pulled up in a white Polo in Linkway.

The victim was threatened with a knife and forced to hand over his property.

The car then drove off towards West Barnes Lane.

Officers from the South West Command subsequently located the car and items from the robberies were recovered.

A 19-year-old man was arrested and charged with five counts of robbery and one count of possessing a knife in a public place.

Detective Sergeant Rob Hegarty, of the South West Command’s burglary and robbery investigation team, said: “We have arrested and charged one man in relation to these robberies but we are keen to identify the other two people involved.

“We are very grateful for the key evidence and support provided already by the young victims and other members of the public and are now urging anyone who saw anything, particularly those with dashcam footage, to come forward.

“Anyone who saw a white Volkswagen car, registration LD19 CXK, in the Wimbledon area between 6pm and 7pm on September 1 is asked to contact police on 101 quoting CAD 6834/01Sep.”
