A Summerville man was arrested minutes after Charleston police say he robbed a downtown pharmacy of prescription pills on Sunday.

Gene Frederick Hart, 47, of Heather Drive faces an armed robbery charge, and he remained in jail Monday in lieu of $50,000 bail.

The robbery at the Rite Aid store at 261 Calhoun St. was reported around 6 p.m., when a man walked up to a pharmacist and said he had a gun, Charleston Police Department spokesman Charles Francis said.

He demanded prescription medication, Francis said.

The robber got three bottles containing 20 pills of Norco, a painkiller, and 40 pills of Valium, which is used to treat anxiety, then he walked out, an incident report added. The value of the pills was about $530, according to the report.

With a description of the robber, patrol officers soon arrested Hart near Jonathan Lucas and Calhoun streets, about a block away from the pharmacy, Francis said.

The police recovered the pills from Hart, but they did not find a gun, the report stated.
