DETECTIVES are searching for four members of an armed gang who stole a more than £25million in cash from a security depot.

The robbers, wearing balaclavas and carrying handguns, threatened and then tied up a number of staff at the Securitas depot in Vale Road, Tonbridge, before loading the money into a white Renault truck.

Securitas said an audit of what had been stolen was taking place but it was known to be about £25 million.

The gang are believed to have driven away in the van shortly after 2.15am on Wednesday. Police were alerted after staff were able to activate an alarm about an hour later.

None of the members of staff were hurt during the robbery. Kent Police officers are talking to staff and conducting a forensic examination of the depot.

Det Chief Inspector Tim Smith, who is leading the investigation, said: “We need help from the public to trace the white Renault truck, which by all accounts is quite new.

"Anyone who thinks they may have seen a vehicle of this type either arriving or leaving the depot, or being driven in the area, should contact Kent Police.

“Also, if you saw anything suspicious or anyone acting oddly around the depot, please contact us.”
