File this one under Metro horror stories.

Metro Transit Police say 25-year-old Northeast resident Lawrence Nathaniel Harris turned himself in on Friday morning after the agency released a warrant for his arrest for allegedly putting a “fluid-filled condom” on a female rider’s shoulder. The incident occurred on a Largo-bound Blue line train on May 24, according to Metro, and the woman wasn’t physically harmed. The agency said in a release yesterday that Harris had made arrangements to turn himself in but didn’t appear.

The suspect is charged with simple assault. Cameras and the victim’s cooperation allowed Metro police to identify him.
