Police investigating the 53 million pound raid at a security depot in Kent said on Tuesday they had arrested two people who were linked to the company which runs the facility, Reuters reported. Kent police said they had arrested one man who was an agency worker sub-contracted to Securitas and a women who had previously worked for the company. They have both since been released on bail. Police have arrested 17 people in total and charged five over the robbery which was carried out nearly two weeks ago when a gang posed as police officers to seize the manager of the Securitas depot in Tonbridge, Kent. The gang then took the manager's wife and son hostage and threatened to kill them unless he helped them get inside the building. Police said on Monday they had recovered at least 11 million pounds in the hunt and a second large amount of money has been found but the total figure is not known yet.
