WILLIAMSBURG - The parents of a Williamsburg girl are demanding justice after she was allegedly sexually assaulted.

The Reese family says their 13-year-old daughter was lured to a park on March 25 by someone she met on Facebook. They say the boy brought the girl to a nearby apartment, where he and three other teens allegedly held the girl against her will with a knife and sexually assaulted her in the bathroom.

After the attack, the victim's family says the teens scribbled their names on her chest and smashed her phone before letting her leave.

The girl's family contacted police when she came home, but family members say investigators did not believe the girl and are not looking for the suspects.

A spokesperson for the NYPD says the case remains an open and active investigation.
