A McDonald’s security guard accidentally shot a woman inside the restaurant after a confrontation with two men at 2:51 a.m. Sunday.

The shot came after the men attacked the security guard working outside of the business located in the 8300 block of Route 1, Prince George’s County Police spokeswoman Nicole Hubbard said. The guard used pepper spray and then fired his gun. The shot accidentally struck a woman inside who was not affiliated with the men. 

Her injuries were not life-threatening, and she is not affiliated with the university, police said.

The security guard is not affiliated with county police and it is not known if the men are affiliated with the university, Hubbard said. The investigation is ongoing.

Hubbard confirmed that the incident occurred outside a business in the 8300 block of Route 1, but would not confirm the restaurant was McDonald’s. That restaurant, however, is the only commercial establishment open there after 2 a.m.
