Perv in 3 gropes

A PROLIFIC pervert groped three people in 30 minutes in the Bronx, including a teenage girl walking with her grandma, cops said Wednesday.

The mustachioed menace was caught on video grabbing one of his victims on May11.

Video shows the man (photo) lurking on Third Ave. by Claremont Parkway in Claremont at about 11:10 p.m., cops said. Three women walk past, and he grabs one by the buttocks. He then followed the 25-year-old woman and rubbed himself against her, cops said.

Twenty minutes later, he targeted a 14-year-old girl on FranklinAve. and fondled her crotch, then grabbed a 19-year-old woman's privates, cops said.
