A sicko grabbed a teen by the hair, attempted to force sex and tried to throw her onto the tracks in a vicious attack on a subway station Saturday.

The 19-year-old victim was on the Manhattan-bound Cypress Hills J-train platform at around 1:20 a.m. Tuesday, when the pervert approached, dragged her by her hair and demanded she perform a sex act.

When she refused, he tried to hurl her onto the tracks, but she kicked him until he gave up and fled.

Police are searching for him.
