POLICE running the Safety Camera Partnership say they are no longer revealing where mobile speed guns are being set up due to potential staff and resource shortages.

Motorists in Warrington are being urged to put on the brakes this summer after top cop Chief Constable Peter Fahy launched an operation to reduce the rising number of deaths and serious injury collisions on the county's roads.

Through June and July, police announced the roads in Cheshire where their weekly mobile enforcement sites would be stationed for the next seven days.

But since the start of August, the Safety Camera Partnership has changed tack and decided to keep the prospective mobile camera locations a secret.

A spokesman said: "Due to a lack of resources, we can't pin ourselves down to a specific location every week.

"Sometimes the site or equipment becomes defective and we need to move somewhere else.

"There are only three mobile vans, and with people sometimes taking annual leave, we are trying to proportionately distribute our staffing levels."
