SPY cameras in bus shelters across Bolton are helping to curb vandalism.

A scheme to introduce CCTV was launched a year ago and figures for 2007 show the number of incidents dropped almost 20 per cent in the borough compared to 2006.

Mobile cameras are placed in trouble spots across the borough and Greater Manchester Passenger Transport Executive (GMPTE) says the cameras have enabled police to make several arrests across Greater Manchester.

GMPTE, Bolton Council, Greater Manchester Police and JC Decaux, which provides the shelters, are working in partnership on the project.

Chief Superintendent Dave Lea, commander of Bolton police, said: "It's very simple. Be warned - commit acts of vandalism and you will be caught and punished."

Eight miniature cameras are in place at shelters across Bolton and can be moved to other sites as required. They record happens in the shelter and provide additional evidence to support existing CCTV systems and mobile vans.

Michael Renshaw, GMPTE's interim service delivery director, said: "Shelter damage not only causes a real nuisance for passengers, it gives a poor impression of public transport and the local neighbourhood.

"We are committed to stamping it out and I am glad we are seeing results."

Bolton's representative on the regional Passenger Transport Authority Cllr Margaret Clare said: "The CCTV scheme demonstrates what can be achieved when pooling our resources with partners.

"It's nice to see that this scheme is achieving results."
