A 20-year-old Suitland, Md. woman was raped early yesterday by two of three men who had abducted her earlier from the Georgetown area, according to police accounts.

U.S. Park Police said the woman and her boyfriend were sitting on a wall at 34th St. NW near the C&O Canal about midnight when they were approached by three men between the ages of 18 and 21 wearing multi-colored sport shirts.

After asking the couple for a cigarette, police said, two of the men drew a switch blade knife and a pistol from their pockets and forced the couple to walk to a nearby telephone booth.

There they robbed the woman of $5 and her escort of $2, police said. One of the men then reportedly told the women's boyfriend, "If you don't want to see her floating the river, you'd better stay here," according to the police.

The men forced the woman into the back seat of a car and then drove to a woods in Oson Hill, Md. near the intersection of Indian Head Highway and Route 495, police said.

After two of the three men raped her there, the woman was dropped off at the intersection, police said. About 3 a.m., a passing motorist picked the woman up and took her to a police station in Oxon Hill.

Park Police were initially informed of the abduction at 12:30 a.m. yesterday by the boyfriend, who phoned them as soon as the three men drove his girlfriend away in the car, police said.

No suspects had been arrested as of late yesterday, police said.
