Hamilton police are looking for a suspect in the latest in a series of pharmacy robberies. A Friday afternoon robbery made 13 so far in 2015, nearly double the seven pharmacy robberies in all of last year.

There have now been more pharmacy robberies in just the four months of 2015 than in any of the previous four years.

Police say a white man around 5-foot-3 in his 20s walked into a pharmacy at 311 Fruitland Road and demanded the pharmacist turn over narcotics. Police didn't say how much the suspect stole or in which direction he ran. There were no injuries and police are still investigating.

Illegal use of prescription opioids is the city's fastest growing drug problem and one that is playing a growing role in thefts and petty crime as addicts seek drugs and money to feed their habits.

The robberies aren't isolated to any one part of town. Hamilton Police published this map showing where the 13 robberies have taken place. One location, 712 Mohawk Rd. E., was targeted three times, and last month police were looking for one suspect they believe was behind all three. 

Police say anyone with information can contact police at 905.546.2991. To provide information anonymously contact Crime Stoppers at 1.800.222.8477 or submit your tips online.
