Scotland Yard has launched an internal investigation after it emerged that an alarm call from the Hatton Garden safety deposit firm robbed last weekend was classed as not needing a police response.
Over 70 safety deposit boxes were forced open after thieves used a heavy duty drill to gain entry to Hatton Garden Safety Deposit Ltd’s offices.
Officers from the Metropolitan Police were called to the premises at 08:10hrs on Tuesday, 7th April after workers discovered the raid.
Earlier this week the force said it was investigating reports of an alarm being activated on Friday, 3rd April.
It has now confirmed that a call was received at the MPS Central Communications Command at 00:21hrs that day.
According to a Scotland Yard statement, “a grade was applied to the call that meant that no police response was deemed to be required.”
An investigation into the grading is now underway.
A Met spokesperson said it was “too early to say if the handling of the call would have had an impact on the outcome of the incident.”
Anyone who has any information about the theft is asked to contact the Flying Squad on 020 8785 8655 or Crimestoppers on 0800 555 111.
