British police say they have arrested seven men over a major heist in London's Hatton Garden jewelry district over the Easter weekend.

The men, ranging in age from 48 to 76, are being questioned in a London police station.

They were arrested Tuesday morning when more than 200 police raided 12 addresses in north London and Kent.

Police said bags containing a significant amount of high-value property were recovered at ones of the addresses.

They said they are confident some of these were items stolen during the burglary, when thieves broke into a vault containing safety-deposit boxes.
