Halton police are hoping a unique baseball cap left at the scene of a recent break-in will lead them to the suspect responsible for a series of smash-and-grab style thefts in Oakville.

Between July 22 and Aug. 11, six commercial break and enters occurred along Rebecca Street and Lakeshore Road, between Trafalgar Road and Felan Avenue.

In each instance, police said, someone smashed the glass doors and stole petty cash.

During one of the break-ins, a ball cap with a unique/distinctive crest on the front was left behind.
