Several items were reportedly stolen from a car parked at Planet Fitness, 111 Black Rock Turnpike, on Thursday between 9:40 and 11:06 p.m.

Police said the culprit got the car's key from an unlocked gym locker, found and entered the car, and then stole the wallet, which contained $20 in cash, credit cards and personal papers. Also reportedly taken were vitamins.

A short while later, one of the credit cards was used at a Super Stop and Shop to buy $439 in vitamins, police said.

The theft remains under investigation.
