A Franklin Square woman who police say struck her ex-boyfriend with a vehicle and then drove away earlier this week, was arrested Wednesday and charged with assault, Nassau County police said.

Kristen Gerakaris, 33, on Sunday around 12:15 a.m., was driving in Floral Park in the westbound lanes of the Jericho Turnpike — east of Emerson Avenue — when she struck her 38-year-old ex-boyfriend, who cops also called a pedestrian, police said in a statement Wednesday night.

The incident occurred after Gerakaris and her former boyfriend “had a dispute” and Gerakaris “left the scene without stopping,” police said.

The victim sustained a head injury. He was listed in serious condition, police said.

Gerakaris was arrested Wednesday and charged with first-degree assault and leaving the scene of a serious physical injury accident, police said.

She is expected to be arraigned Thursday, officials said.
