(Update at 2:25 p.m.) A woman was raped on the side of one of the bike trails along Four Mile Run last night (Tuesday), according to police.

Investigators say the incident happened along the trail while it was still light outside — between 7:30 and 8:00 p.m. The woman, 23, was jogging by trail mile marker 44, near Glencarlyn park, when a man, whom she had seen along the trail earlier, stopped her. He took out a 6-inch kitchen knife, dragged her into some tall vegetation, and took off her clothes and underwear, according to Arlington County Police spokesman Dustin Sternbeck.

At one point the woman tried to run away but the attacker restrained her and threatened her with the knife, Sternbeck said. After the man was done sexually assaulting the victim, she ran home and drove herself to the hospital. Hospital staff called police at 8:49 p.m. In addition to the injuries from the sexual assault, the woman also sustained scratches to her wrists, Sternbeck said.

The man is described as a clean-shaven Hispanic male, between 5’5″ and 5’6″, 140 pounds, about 30 years of age. He had short black hair and brown eyes. The victim said he had a small head, a high-pitched voice, spoke limited English, and was wearing a green shirt that might have said George Mason University on it.

The victim has been an Arlington resident for 6 months, Sternbeck said.
