CHICAGO (CBS) — Police in northwest Indiana have broken up a theft ring that operated in the parking lots of home improvement stores.

The thefts began in April. On at least three occasions, men dressed in yellow safety vests to blend in with legitimate construction workers, watched as they went inside, and then broke into unattended vehicles to steal the workers’ tools.

Schererville Police Cmdr. Brian Neyhart said one victim caught the thieves red-handed, and confronted them on April 15. He spotted the suspects taking tools from his vehicle, and putting them in the trunk of a black sedan.

“The passenger had gotten in, and was holding one of [the victim’s] tools. It was a drill that [the victim] believed was his. He tried to reach inside the window, and grabbed it. The guy who was sitting there, he yelled ‘Give me a pistol,’ so he pulled his hand back out of the car, and they drove away,” Neyhart said.

On May 11, the thieves took $700 worth of tools from a truck at Menards.

The officers saw power tools in the trunk when the suspects opened it, and as a police officer drove past the car, the suspects closed the trunk.
