Waterloo Regional Police have arrested the man they believe to be behind a string of pharmacy robberies in Cambridge.

Three pharmacies – one on King Street East which was hit twice, as well as one apiece on Holiday Inn Drive and Waterloo Street – had been robbed in the past month.

In each case, the male thief had made off with prescription painkillers.

Police say information provided by the community helped them arrest a 25-year-old man believed to be behind the robberies.

He faces four counts apiece of robbery and wearing a disguise with intent to commit a crime, and police say further charges are pending.
