CLARKSVILLE, Tenn. (AP) -- Police in Clarksville believe the same man committed three pharmacy robberies in two days, taking prescription painkillers after showing a handgun.

A third drug store was held up Monday afternoon by a slender white man who had asked a pharmacist about various medications and pulled the weapon when he was told the pharmacy stocked Oxycontin. The robber was described as being in his 20s or early 30s, about 5-feet-7 and having a triangular tattoo on the back of his neck.

That robbery was at a Walgreens. Earlier Monday, a Rite-Aid was robbed of medication. Another pharmacy was hit on Sunday.

Police ask that tips be phones to (931) 645-8477.
