Milford police Thursday are looking for the man who robbed several gym lockers at Planet Fitness gyms across southwestern Connecticut.

Investigators say they are worried about a stolen police badge that could be falsely used to commit even more serious crimes.

Gym employees say a man posed as member to enter the men?s locker room. They add that he then used a bolt-cutter to break into at least five lockers, stealing cash, credit cards and a New Haven police badge.

A similar case allegedly occurred at a Planet Fitness in East Haven, where a surveillance photograph revealed a man using a credit card swiped in the robbery.
