One mystery remains unsolved: Why Takoma Park Police continue to employ the phrase "private parts" in their sex crime coverage. Full police press release after the jump:

Chief Ronald A. Ricucci from the Takoma Park Police Department announces the arrest of Oritse Ayu, 29, of Baltimore, Maryland, for 2nd degree assault and indecent exposure.

On October 9, 2010, Takoma Park Police responded to the 7600 block of Takoma Avenue (Montgomery College) for reports of a male subject who assaulted a female who was sitting in the school library. The victim was sitting in the library when the male subject walked past her and ejaculated on her arm. When the victim turned to the subject, he was standing behind her with his "private parts" pulled out of his pants.

The victim was able to get a good look at the subject before he fled the scene. The victim immediately went to the reception desk to report the incident. The receptionist contacted campus security and the Takoma Park Police Department. While contacting police, the subject re-entered the area where the victim was standing and spoke to her and then fled again from the library. The subject is unknown to the victim. DNA evidence was obtained from the victim. Campus security chased the subject on foot through the campus and witnessed him enter a maroon, four-door sedan displaying Maryland tags. The subject fled the area on Fenton Street towards Takoma Avenue.

Working with surveillance video obtained from the college campus, detectives were able to identify Ayu as the suspect. With the assistance of Montgomery County’s Repeat Offender’s section (ROPE), Ayu was located in Baltimore, Maryland, arrested and transported to Takoma Park, Maryland. Ayu has been charged and transported to the Montgomery County Central Processing Unit.
