The Port Moody Police Department says it is investigating a possible ring of thieves that has been targeting wallets and purses left in parked vehicles at trailheads and parks.

The investigation dates back to June 21 when the force received a report of a theft from a vehicle off Saint Johns Street.

"A purse was stolen and the associated credit cards were used at businesses nearby," wrote Sgt. Bradley Sheridan in an email to CBC News.

Arrest, stolen credit card charges

A review of surveillance video led police to Mandy Haley, who was arrested and charged with the unauthorized use of a credit card and possession of a stolen credit card.

Haley remains in custody and is scheduled to appear in provincial court in Port Coquitlam on August 22.

As part of the investigation police executed a search warrant in Surrey and discovered that, "individuals are actively targeting vehicles parked at trailheads and parks," in Port Moody, according to Sheridan.

"We recommend that people ensure they don't leave anything in their vehicles," he said.

"‎Wallets and purses are favourite targets for thieves as they contain personal information that can lead to further victimization."
