An 18-year-old District man who escaped from a detention facility in South Carolina in April is on the loose again after fleeing authorities at Baltimore-Washington International Marshall Airport on Sunday, officials said.

The man was returning to the District from a placement facility in Salt Lake City for a Monday hearing in D.C. Superior Court, according to the city’s Department of Youth Rehabilitation Services.

Authorities have not named the man. He has been charged as an adult with assaulting a police officer in a May 6 incident in which he allegedly hit a correctional officer with a broom at the New Beginnings secure detention facility, according to D.C. Council member Jim Graham (D-Ward 1), who oversees the department, and another source.

The man escaped Sunday at about 4:30 p.m after telling a guard he needed to use the bathroom, Graham said. It was at least the third time he has escaped authorities, sources said.

On April 20, the man and three other detainees ran away from Palmetto Summerville Behavioral Health center in Summerville, S.C., a 60-bed DYRS placement facility, Graham said. The center treats teens with sexually aggressive behavior, substance abuse problems and other behavioral issues.

He was caught the next day and sent to New Beginnings, the secure facility in Laurel for District youths. Two weeks later, he was charged with assaulting a guard there, Graham said. He then was sent to to the Cottonwood Treatment Center, a secure, psychiatric facility in Salt Lake City, for several weeks, according to sources.

Authorities described the man as African American, 5-feet-9-inches tall and weighing about 150 pounds. He was last seen wearing a white T-shirt and blue shorts. A photograph was not released.

Graham said that police should be able to release a photo of the man, who is charged as an adult. A bill that would allow for the release of the name and photograph of any youth who escapes from a secure detention facility failed to pass a council vote several weeks ago as an emergency measure. It is now before the council.

“How can we help find someone if we don’t know what he looks like?” Graham said.

Currently, police must ask a Superior Court judge for an order to release photographs of wards of DYRS who are on the run.

There have been several high-profile escapes of District youths this year. In one case, Treyvon C. Carey, 18, reportedly beat a guard and ran from New Beginnings. It took police several weeks to find him.
