24-year-old Jason Colliver of Miller Walk, off Stamford Street, was on Friday sentenced to 10 years imprisonment at the Middlesex Guildhall Crown Court after he pleaded guilty to three robberies in south London and the Home Counties.
On 12 November Colliver pleaded guilty to a robbery on 8 March 2002 at Siemens, Hemel Hempstead; a robbery on 15 March 2002 at IKON, Ullswater Crescent, Coulsdon and a robbery on 5 April 2002 at Wincar Nixdorf, Wokingham, Berkshire. Colliver was a member of a gang of violent robbers.
Detectives from the Metropolitan Police Territorial Police Crime Squad carried out an undercover operation, codenamed Operation Neptune and Hirvine, targeting a team of criminals engaged in violent robberies throughout London, the Home Counties and Europe on office premises.
Millions of pounds worth of computer equipment was stolen. The offenders forced entry to offices and assaulted and tied up security officers and staff. The police operation culminated in the arrest of four suspects on 5 April 2002 as they were robbing the offices of Wincar Nixdorf, in Wokingham, Berkshire. The security guard was found tied up and bleeding from a head wound. Jason Colliver escaped and was arrested later.
Police officers from the Metropolitan, Hertfordshire, Surrey, Cambridgeshire and Thames Valley forces worked closely together to gather the evidence necessary to prosecute the offenders. In all six members of this violent criminal gang were brought before the courts. Each of them has now been convicted and sentenced.
