A sicko sexually assaulted a Queens woman on Christmas Eve, police said.

The creep followed the 47-year woman off a bus in Springfield Gardens near 140th Avenue and Coombs Street about 6:40 p.m. Monday, and molested her on the sidewalk before fleeing.

Surveillance video captured the goon after the attack. Cops say he is between 18 and 24 years old, and about five foot eight to six feet tall. He was last seen wearing a dark-colored coat and pants, white sneakers, and carrying a black backpack.
