In the last hour police have confirmed that £53 million pounds was stolen in last week's robbery at the securitas cash depot in Tonbridge. And they've said they're still confident they're still on the trail of the robbers - another four men are in custody tonight. It's now five days since the gang raided the depot and made off WITH the cash. Since then, there have been a number of armed police raids. Seven vehicles thought to be involved in the robbery have been found. But police say they still don't know the whereabouts of the lorry that was used to take the cash from the depot. And despite more than a thousand calls to their hotline, they're still anxious to hear from the public.
