WASHINGTON — A Gaithersburg High School employee inappropriately touched three people, two of whom are juveniles, Montgomery County, Maryland, police said Wednesday.

And investigators are asking Gaithersburg High parents to talk with their kids about possible interactions.
Ancelmo Osmin Diaz, 59, is charged with one count of second-degree assault; six counts of sexual abuse of a minor; and seven counts of fourth-degree sex offense.
Last week, a juvenile told authorities that Diaz, a building services employee at the high school, had inappropriately touched her for about three years. Another juvenile told investigators that Diaz had inappropriately touched her for five years. And an adult told police that Diaz had inappropriately touched her when she was 18.
Investigators said they believe all of the incidents occurred in Diaz’s residence.
During an interview, Diaz “made statements partially admitting to the inappropriate touching,” police said. A warrant was obtained Thursday, and he turned himself in to police on Tuesday.
Parents who believe their child had inappropriate contact with the suspect are asked to call Montgomery County police’s special victims investigation division at 240-773-5400.
