D.C. police are searching for three men who authorities believe robbed drugstores on Capitol Hill and in two other neighborhoods this month, taking money and prescription medication. The men are masked and armed, and struck during the morning and early afternoon.

The latest robbery occurred Friday at Morton’s Pharmacy, in the 700 block of East Capitol Street NE on Capitol Hill.Police said three men wearing hoods and at least one carrying a gun took money in the 11:50 a.m. attack.

On Jan. 17, police said three men robbed Grubb’s Pharmacy, in the 1800 block of Martin Luther King Jr. Avenue SE in Anacostia. Police said the men walked into the shop about 9:35 a.m. wearing hooded sweatshirts and masks. One man pointed a gun, and at least one had a backpack.

A surveillance video shows them walking directly to the pharmacy in the back, where they kept an employee on his knees as they rifled through the stock and medicine drawers.

On Jan. 3, police said three men robbed Flexcare Pharmacy in the Fort Davis Shopping Center in the 3800 block of Alabama Avenue SE. Police said it occurred about 12:45 p.m. Surveillance video shows two the men, both wearing masks and hooded sweatshirts, vaulting over a counter. One was carrying a gun in his right hand.

Detectives in Prince George’s County believe the same crew might be responsible for a daylight robbery of a District Heights pharmacy on Jan. 10. In that case, a masked gunman, another masked man who had pepper spray and a third man leapt across the counter about 11:15 a.m., pointed a gun at an employee before they stole cash and rifled shelves for medications, county police said Thursday.

No employees were injured.
