GLEN ELLYN, Ill. (STMW) — A 35-year-old Wheaton man has been arrested for the armed robberies of prescription drugs from west suburban pharmacies in two separate incidents.

In the first robbery, which took place at the Walgreens at 324 Roosevelt Rd. in Glen Ellyn about 12:30 p.m. May 16, the man brandished a knife at the pharmacy counter and demanded a specific drug — Opana ER, a release from Glen Ellyn police said.

Employees handed over about 50 Opana pills and the man fled the store, the release said.

No one was hurt in the incident. According to the website , Opana is in a group of drugs called narcotic pain relievers. Similar to morphine, Opana is used to treat moderate to severe pain. The extended-release form of this medication is for around-the-clock treatment of pain.

Last week, Winfield police officers developed information that led them to 35-year-old Jason McGee of Wheaton, the release said.

Winfield officers worked with Glen Ellyn officers, with assistance from Wheaton police, and McGee, of the 600 block of Aurora Way in Wheaton, was taken into custody without incident Friday afternoon.
