A 16-year-old Washington girl told police a story much like one they had heard earlier this week: She was abducted, sexually assaulted and held captive in Prince George's County.

Then, last night, the girl recanted her story and said she made it up after spending two days with her boyfriend, police said.

The 16-year-old's initial story resembled an incident that began Monday night when, police said, a 19-year-old Suitland woman was kidnapped at knifepoint while walking to a store, forced into an abandoned garage and raped repeatedly before she escaped 32 hours later.

Prince George's County police spokeswoman Diane Richardson said last night that "we believe the {Suitland} attack occurred, and we continue to pursue it vigorously."

Police said no charges would be brought against the 16-year-old, who they said made up the story of being abducted on Tuesday and held against her will in a house in Upper Marlboro because she "didn't want to get in trouble with her parents."

"It's unclear whether she heard about the other attack and it gave her the idea," one official said. "But she was obviously a scared girl just trying to stay out of trouble. That's why she's not being charged."

Police said they routinely field rape reports that are later recanted for one reason or another.

"We take each report seriously and check out every one," the official said.

"Unfortunately, we do get a good many people who say they were raped when they actually weren't. Many times it's because they are afraid they'll get into trouble with their parents or their boyfriends."
