Four teenagers are in police custody and a fifth suspect is being sought in connection with an alleged group rape of an 18-year-old woman in Brooklyn.

The NYPD says two teenagers surrendered and two were apprehended. Charges are pending against the 14-year-old, 17-year-old and two 15-year-olds suspects.

Authorities say the victim was accosted Thursday night as she and her father walked inside Osborn Playground in the Brownsville section.

Police say one of the suspects pointed a gun at the father and told him to leave.

Authorities say each man raped the woman. The attackers had already fled when the father returned with two police officers.

The woman was treated at Kings County Hospital and released.

Mayor Bill de Blasio said he was "disgusted and deeply saddened by the horrific attack."
