Ram-raiders have smashed through the doors of Selfridges in central London before stealing designer handbags.
A security guard was threatened with a knife and another driven at when they attempted to stop the break-in at the Oxford Street store in the early hours of Tuesday.
The four assailants were captured on CCTV before they fled in another car, a white VW Golf. No arrests have been made.
A spokesperson for Selfridges said: “Nobody was injured and the police are investigating. The store is continuing to trade as normal.”
DC Tom Aylward said: “This raid was targeted and lasted a matter of minutes. My team are busy collecting witness accounts and recovering vital CCTV footage of the burglary at the store and of the suspects leaving the scene.
“I’d like to appeal for those who may have been in the area at the time and saw the individuals involved, either at the scene or fleeing, to get in touch with police and send us any images and footage that they may have.”
