A man was arrested Friday, accused of groping minors who were on their way to school during three separate incidents in the Bronx this week, police said.

Between 7 and 8:15 a.m. on Wednesday, three girls, ages 11, 13 and 15, each reported to their school administrators that they had been inappropriately touched by a man while walking alone to their classes.

Police arrested Alvin Ortiz, 31, for groping all three victims. In the third case, involving the 13-year-old, he had his genitals exposed when he approached her, police said. Surveillance footage shows Ortiz entering a black Chevy Impala and fleeing the scene following the attacks.

All three incidents took place within the confines of East 172nd Street and Wheeler Avenue in Soundview. It was not immediately clear whether all three victims attended the same school.

Ortiz was charged with sexual abuse, forcible touching and acting in a manner injurious to a child, police said.
