The Washington Post reported Friday that Charles R. Bouma, 43, of Beltsville, Md., was driving alongside a school bus when he allegedly exposed himself to students from the Academy of the Holy Cross, a private girls school in Kensington, Md.

“He was driving alongside the bus and proceeded to pull his pants down and expose himself to the students,” Montgomery County police spokeswoman Melanie Hadley told the Post. “He then followed the bus and drove around each side of the bus, causing a commotion and continuing to expose himself and engage in a personal sexual activity.”
