The Western Region OPP Crime Unit is asking for the public's help in identifying a suspect linked to three robberies across southwestern Ontario.
They've released surveillance photos from the incidents.
The Paul Marley Pharmacy in Wyoming was robbed March 7, and police believe the same suspect robbed the credit union in Parkhill March 6 and Royal Oasis Pharmacy in Lakeshore February 16.
Sarnia police were investigating a possible connection to an attempted robbery at knifepoint at the Vidal Pharmacy less than an hour before the Wyoming holdup.
The suspect is described as a white male, 5' 11'' tall, about 170 lbs. with a thin build.
In each case, he wore a grey toque concealing his entire face, a black cloth jacket with a hood pulled over his head, grey jogging pants, white running shoes and very distinctive dark coloured work gloves. The suspect was also carrying a black backpack, and demanded cash and narcotics from the employees.
Anyone with information is asked to call the OPP or Crime Stoppers.
