NEW YORK (AP) — Four teenagers were taken into police custody in connection with an alleged group rape of an 18-year-old woman at a Brooklyn playground, an incident that the mayor called a "horrific attack."

Police said Sunday two teenagers surrendered and two were apprehended. Charges were pending against a 14-year-old, 17-year-old and two 15-year-olds. A fifth suspect is still being sought.

Authorities said the woman was accosted just after 9 p.m. Thursday as she and her father walked inside Osborn Playground in the Brownsville section of Brooklyn.

Police said there were five suspects, and one pointed a gun at the father and told him to leave. Each man raped the woman, police said. The father returned with two police officers, but the attackers fled.

The woman was treated at Kings County Hospital and released.
