SNEAKY thieves are on a crime spree in Huddersfield.
Police say victims are making life easy for the thieves by leaving purses and wallets within easy reach.
Sgt Tim O'Sullivan said: "The number of these crimes has increased dramatically in the last three weeks. We are having up to four a day.
"These thieves can easily be thwarted if people took the simplest precautions."
He urged people to make sure their purses and wallets were kept hidden in inside pockets, preferably ones with a zip or button.
Too many people have them in back pockets or leave them on top of shopping bags, where they can be easily seen and quickly stolen.
Sgt McSweeney added: "Some of these thieves work in gangs and travel from big cities into towns like Huddersfield to steal.
"We caught a gang from Leeds a while back.
"The gangs tend to work in groups. One or two bump into victims or jostle them, and while they apologise the thief strikes.
"The message is simple. Always be aware who is around you."
