A north-side drugstore held up Monday night was the third pharmacy in a week to be robbed of a painkilling drug.

About 6:45 p.m. Monday, a man entered Walgreens at 5830 N. Clinton St. at St. Joe Center Road and told the pharmacist to “Give me all your Opana or I’ll start shooting,” according to a Fort Wayne police report.

The pharmacist gave the man about 200 pills and the man ran out the front door of the store, police said.

Witnesses said the man fled to a nearby gas station across the street before he got into a car driven by a woman, the report said.

The robber was described by police as about 5-foot-6, white or Hispanic and wearing all black with a black mask across his face.

A robber took Opana from a Walgreens at 10412 Coldwater Road during a Jan. 31 robbery and from a pharmacy inside the Scott’s grocery store at 4120 N. Clinton St. on Jan. 30. Opana is a brand name for oxymorphone, a powerful painkiller.

Police are not saying whether they believe the robberies are connected.

Anyone with information is asked to call the Fort Wayne Police Department at 427-1222 or CrimeStoppers at 436-7867.
