It happened around 6:00 Sunday.
Police say the suspect entered the store and walked directly to the pharmacy.
Once there, police say he placed a handwritten note on the counter that said "No alarm. I have a gun." However, police say, no weapon was displayed.
The man ordered the pharmacist to hand over all of the Roxicodone and Oxycontin. He then grabbed the five bottles, and the demand note, and fled the store.
The suspect is described as a white male "very skinny" (approx. 150lbs) and 5'8" to 5'10" tall.
Police say the same man may have robbed the same store twice back in July.
The suspect may be driving a dark colored Jeep Grand Cherokee Laredo.
