UNDERCOVER officers impersonated pickpockets to send a message to shoppers yesterday.

They were taking part in a crime prevention operation in Chatteris which highlighted the risk of falling victim of pickpockets.

Instead of stealing from shoppers, officers dropped postcards into their bags to show how vulnerable their valuables were and gave out crime prevention advice.

Officers placed rear view hangers in 15 unlocked cars declaring that no valuables were inside and three cyclists were spoken to about leaving a cycle unlocked whilst they went into a shop.

The operation was held following a spate of purse thefts in the town.

Crime Prevention Officer Julie Bailey said: “We identified four people who were at risk of having their purse stolen. When we spoke to them they were shocked to discover that a note had been dropped in their bag without them realising.

“Unfortunately we weren’t able to follow up every card drop, so some people would have discovered the warning message later on.

“We also noticed a number of drivers had left windows open after parking their cars, and some vehicles were even unlocked.

“While we all want to keep cool in the current hot weather, please remember to shut your windows and leave your car locked.

“Our message is simple: If it’s left on show expect it to go.”
