Fairfax County Police have arrested an 18-year-old Marshall High School student and charged him with one of several sexual assaults near the Dunn Loring Metro station.

Michael Scott Acosta, who lives in an apartment complex near the area, was taken into custody at his home in the 2700 block of Pleasantdale Road in the Merrifield area and charged with abduction with intent to defile, rape and two counts of forcible sodomy in connection with an attack on Sept. 21, according to a county police news release.

Police said that possible charges against Acosta for two other attacks, on Oct. 7 and Oct. 23, "will be determined upon consultation with the Commonwealth Attorney's Office."

The first attack occurred the night of Sept. 21. A 22-year-old woman walking north from the station past Stenwood Elementary School was grabbed and raped in woods near the school, police said.

Two more attacks occurred Oct. 7, south of the station, near the Merrifield Apartments. One woman was grabbed and knocked down, but her attacker ran when she screamed. An hour later, in the same neighborhood, a similar-looking man forced a woman into a secluded area and raped her, police said.

In another assault, on Oct. 23, a 26-year-old Fairfax County woman fought off an attacker who had entered her second-floor bedroom through an unlocked deck door.

Police said the arrest came after they spotted a man meeting the description of the attacker who was behaving "suspiciously" near the Metro station.

A detective spoke with the man and learned his identity; the investigative team was able to connect him to a piece of evidence found at the scene of one of the crimes. Further evidence was obtained after searching his residence.

Acosta is being held at the county Adult Detention Center without bond.

County police said they were assisted in the case by the Metro Transit Police, the Loudoun County Sheriff's Office, the Spotsylvania Sheriff's Office and U.S. Postal Inspectors.
