London ? Detectives investigating what could the biggest cash robbery in British history recovered a “significant amount” of the money Friday from a van just miles from the heist site, police said.

The armed robbery Wednesday at a cash storage depot in the town of Tonbridge in Kent could have netted as much as $87 million, police have estimated.

Some of the stolen money was discovered in black sacks stashed in a van parked at the Ashford International Hotel, about 10 miles from Tonbridge, near the Channel Tunnel in southeastern England. But investigators did not reveal exactly how much they had found.

Television footage showed officers wearing protective clothing removing large black sacks from the white van.

Police said forensic experts were going over the van in search of clues.

Earlier Friday, a gang using similar tactics stole $350,000 from a bank in Belfast, Northern Ireland. Both of this week’s robberies used so-called “tiger kidnapping” tactics, when a gang takes an employee’s family hostage to force the employee to help rob their own business.
