Windsor Police have a 45-year-old man in custody after a slew of thefts from four local pharmacies in recent weeks.
Investigators appealed to the public for information after issuing a photo of a suspect in 13 separate thefts between April 2 and April 14.
Police believe up to $1,000 in merchandise was taken in each incident.
When staff attempted to intervene, the suspect became aggressive.
On Tuesday, officers arrested the suspect on Huron Church Road between Totten Street and Malden Road.
