A SMASH-and-gang escaped with up to £1m in gems after driving a truck into posh jewellers Tiffany & Co’s signature store.
The raiders reversed the white flatbed Ford lorry through the front window of the shop in Sloane Square in Knightsbridge, west London, at 2.56am today then fled on mopeds with their booty.
Police secured the store as crime scene investigators examined the abandoned truck for clues.
Officers were seen photographing at least two sets of footprints left on the pavement among the shattered glass.
They appeared to have been left by someone wearing designer trainers.
Lisa Smith, 44, who lives nearby and whose boyfriend recently bought her £7,000 engagement ring from the store, said: “I’m shocked, absolutely shocked that such a fundamentally strong security system didn’t work.”
Det Insp David Watkinson, of the Metropolitan Police, 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.
“We are particulary keen to hear from passing motorists who may have captured what took place on dash-cam footage.”
A Scotland Yard spokesman said: “No arrests have been made. Enquiries continue.”
Tiffany & Co had not commented tonight.
