A group of smash-and-grab thugs slammed into a London Tiffany’s shop with a van — and barged inside on mopeds, swiping several items from the high-end jewelry retailer, according to a new report.

The bandits used a transit van to smash the front window of the flagship store just before 3 a.m. Friday, authorities told Metro UK.

Then raiders on mopeds swiped “a quantity” of items from the window of the luxury jewelry store, police said.

The transit van remained at the scene, and no arrests were immediately made.

The haul was worth less than a million pounds — equivalent to about $1.3 million, police told The Sun.

The store was closed for the day Friday.

“All I know is a tipper truck backed into it at 2:50 in the morning,” a property manager told the outlet. “It would have quite a big, big force.”
