London 2012: Police complete pre-Olympic security drill on M3 in Hampshire
An Olympic security drill on the M3 in Hampshire which involved a large police presence has now ended.
The Hampshire and Thames Valley forces carried out an exercise on the hard shoulder of the northbound carriageway near Fleet Services.
It aimed to test how officers would deal with any threat made to the Olympic Route Network at the London 2012 Games.
Search officers, the roads policing unit and the dog unit were involved.
The exercise, which was carried out during the late morning, involved four vehicles moving slowly on the hard shoulder for about an hour, police said.
PC Georgina Laycock, of Hampshire Constabulary, said: "It is important to note that there is no known threat to, or specific intelligence, regarding the motorways, we are just practicing our response procedures to ensure that we are prepared for any eventuality and able to respond effectively, swiftly and safely."
Weymouth and Portland in Dorset will host the Olympic sailing events during the 2012 Games.
Earlier this year it was revealed that about 1,500 police officers could be deployed to cover the 2012 Olympic and Paralympic rowing events at Eton Dorney Lake in Buckinghamshire.
Thames Valley Police covers Berkshire, Buckinghamshire and Oxfordshire.
