A cleaning woman was sexually assaulted in a Gaithersburg apartment complex Wednesday morning.
About 9:30 a.m., a 28-year-old woman was assaulted in an apartment complex in the 700 block of Quince Orchard Blvd, police said.
A cleaning woman for the condos went into a laundry room on her regular routine, but someone followed her. Once inside the room, the man apparently closed the door then pulled out a knife and sexually assaulted the woman.
After the attack, the man took off in an unknown direction.
Wednesday night, warnings could be seen hanging in the entries of numerous buildings at the Potomac Oaks Condominium and residents were bolting their doors.
"[I feel] unsecure," said Jutta Evans, a Potomac Oaks resident. "I'm a little scared."
Residents say the attacker is not one of their neighbors.
While the laundry room has a lock, the entrance to the building is left open.
