British police continue to question nine men arrested over one of Britain's biggest ever jewellery raids.
The men, aged between 43 and 76, were arrested in and around London on Tuesday.
The well-planned raid on London's Hatton Garden jewellery district last month saw the contents dozens of safety deposit boxes taken, with a reported value of as much as $300m.
Police say they have recovered many of the stolen items.
No one has yet been charged.
