An armed man stole 300 painkillers from an M Street pharmacy on Monday, according to a Metropolitan Police Department report.

The robber, estimated to be about 30 years old, approached the pharmacist on duty before 11:00 p.m. and handed him a note that read “I have a gun, give me the Percocet,” according to the report. The hydrocodone pills were stolen from the CVS at 2240 M St., which features a 24-hour pharmacy.

Police reviewed the store video and determined that the man was aided by a woman who had originally been identified as a witness.

In April, two men stole 642 hydrocodone pills from the pharmacy at a CVS at 21st and E streets after it had closed. Hydrocodone, commonly marketed as Vicodin, is the most abused prescription pill by teenagers, Drug Enforcement Administration spokeswoman Barbara Wetherell said in April.
