An intruder sexually assaulted and robbed a 27-year-old woman inside her Centreville home Sunday, Fairfax County police said.

The woman awoke as the attack was in progress around 3 a.m. in the 13000 block of Winding Oak Circle, police said.

The woman challenged the man and he fled on foot, police said. An investigation also revealed electronic equipment had been stolen from her residence.

The suspect apparently gained entry through an unlocked door. He was described as possibly Hispanic, 25 to 35, and 5’7’” tall. He was of medium build and was wearing a dark hoodie and dark pants.
