A man has been arrested in the 2007 rape of a hotel worker in Gaithersburg, Montgomery County police said.

Police said a recent DNA match led authorities to 28-year-old Darren L. Marshall, of Upper Marlboro, in the December 22, 2007, attack. A housekeeper entered a room at the Holiday Inn located at 2 Montgomery Village Ave. at about 9:45 a.m. that day to clean. She was assaulted and raped inside the room, police said, and the attacker then fled the hotel.
