Police failed to respond to Hatton Garden alarm
Police were told an intruder alarm had gone off at the Hatton Garden safe deposit box but decided it did not require a response.
About 70 safety deposit boxes were opened at the Hatton Garden Safe Deposit Ltd in central London over the Easter Bank Holiday weekend.
The Met Police said they received a call on Friday 3 April at 00:21 BST.
Officers are now investigating why the call was given a grade that meant no police response was deemed necessary....
