It was a smash and grab.

Police are searching for a suspect they believe used a large rock to bust open the front door of a Queenston Road pharmacy on Sunday.

The thief made off with a variety of medication from the Medicine Shoppe at 840 Queenston Rd. around midnight, police said in a media release Monday.

Police said the suspect was wearing dark pants and a black hoodie.

The BEAR Unit continues to investigate.
