A pervert grabbed a 9-year-old girl’s buttocks in Central Park and then tried to pick her up — but she was able to get away, police and sources said Wednesday.

The man, depicted in a sketch released by cops, approached the girl and grabbed her backside over her clothes around 3 p.m. Monday at East Drive and East 75th Street, cops said.

He then tried to pick her up, but she managed to escape, police sources said.

The man is described as about 25 years old, between 5 feet 7 and 5 feet 9, and between 150 and 160 pounds. He was last seen wearing a black hooded sweater, black sweatpants and a blue surgical mask.
