Tiffany & Co ram raid: Van driven into Sloane Square store
"Brazen" ram-raiders smashed a van into the front of Tiffany & Co in London before they fled on mopeds with "significant" amounts of jewellery.
The Ford Transit was driven into the shop in Sloane Square, Knightsbridge, at about 03:00 BST, before being abandoned, the Met Police said.
No arrests have been made and police are appealing for witnesses.
In a statement, Tiffany & Co said it "cannot comment on what may have been taken or its value".
The company added it was "working closely with the authorities in this ongoing investigation."
Workers have put barriers around the broken window at the shop on Sloane Street.
Det Insp David Watkinson, said: "This was a brazen and targeted incident which has resulted in a significant amount of items stolen.
"Although the incident took place overnight, it is a busy well-lit area."
