Six people have been arrested and 12 vehicles recovered following a string of thefts from the Trafford Centre.
Greater Manchester Police say no vehicle thefts have been reported at the shopping centre for four weeks, following the launch of Operation Lexford, which was rolled out to tackle the issue.
Officers say they are 'continually providing a visible deterrent in shopping centre car parks to stop those thinking of targeting vehicles', and their operation has 'fulfilled its aim to robustly tackle vehicle crimes in Trafford'.
But they asked vehicle owners to take a number of preventative measures to help keep their car from being targeted, including ensuring it is locked, investing in a tracking device, and urging them not to leave valuables on display.
Inspector Leanne Kennedy of GMP’s Trafford District, said: “This operation is an excellent showcase of GMP’s continued commitment to tackling vehicle crime across Greater Manchester.
“As part of the operation, there has been an increased police presence at Trafford Centre and we have been holding weekly police surgeries with focus on providing people with tailored crime prevention advice and we have been working in partnership the Trafford Centre security team.
"We will continue to work to bring offenders to justice, but I would ask that the public to help us to help them, by being vigilant when visiting the Trafford Centre, and to follow our simple crime prevention advice found on the crime prevention page on our website."
