A Silver Spring middle school teacher has been accused of sexually abusing three students on campus.

Montgomery County police began the investigation last month after administrators at the A. Mario Loiederman Middle School reported that two 11-year-old girls said they were inappropriately touched by their teacher, Benjamin Robert Cano. Police said they later learned of a 12-year-old girl who said she also was touched by Cano. The alleged incidents happened between August 2012 and May 2013 during school hours.

Cano, 33, of Edgewater, was arrested and charged with three counts of sexual abuse of a minor and three counts of committing a third-degree sex offense.
