A perv allegedly sexually abused two young girls in a Bronx building last month — and cops believe he may have other victims.

The two victims, 6 and 10, were playing in the lobby of the building at Grand Concourse and East 167th Street around 7 p.m. Aug. 14 when 62-year-old Washington Jaramillo approached, touched both of them on the buttocks and kissed the younger girl on the lips, authorities said.

He then took off, but was arrested a short time later, according to police.

He was charged with sex abuse, forcible touching and acting in a manner to injure a child.

Now police believe he may have additional victims and released his mugshot.

Anyone with information should call the NYPD’s Crime Stoppers Hotline at 1-800-577-TIPS (8477), or for Spanish, 1-888-57-PISTA (74782).
