Thieves used a gas canister to blow apart a cash machine in east London and make off with its contents.
Debris was left strewn across Ripple Road after the crooks blasted the machine apart in the early hours of Monday.
Police believe three men were involved, fleeing on motorbikes with their haul after destroying the cashpoint.
It comes after several cash machines were destroyed in explosions in west London last month, and detectives fear someone – including thieves – could end up seriously injured.
There have been no arrests.
Anyone with information should call police via 101 or Crimestoppers anonymously on 0800 555 111.
