Montgomery County Police have charged a Frederick man with sex offenses that occurred at a school where he taught. Timothy Vincent Krupico, 30, was served with a warrant on Thursday morning, charging him with two counts of sexual abuse of a minor, and other sexual offenses.

Detectives with the Family Crimes Division received information on Wednesday from two, 11-year-old girls, alleging Krupico inappropriately touched them, and forced both of them to do the same to him. Authorities say it happened between September, 2012, and February, 2013. At the time, Krupico was the girls' teacher at Meadow Hall Elementary School in Rockville.

Police list Krupico's address as the 6900 block of Rocks Court.
