After a group of four juveniles broke into 11 Boynton Beach patrol cars at the police station and stole gear and ammunition, the Police Department took a close look at its security measures, reported the Palm Beach Post.

It was later discovered that the breaks-in were accomplished with a police fleet key, capable of opening all patrol cars in the fleet. A spokesperson for the Boynton Beach Police Department noted that the break-ins were connected to another police car burglary in nearby Palm Beach Gardens, but neither agency knew that such a key existed.

Security is a growing concern for police agencies in the area. Earlier this year, a Palm Beach County sheriff’s deputy was reprimanded after an assault rifle was stolen from his unlocked cruiser, and another deputy was ordered to take remedial training after a loaded handgun was stolen from his personal vehicle, reported the Palm Beach Post.
