Police said on Sunday four teenagers suspected of participating in a gang rape at a Brooklyn playground were taken into custody while a fifth man remains at large. Five young men, armed with a gun, approached an 18-year-old woman and her father at the Osborn Playground in Brownsville, Brooklyn on Thursday night. Police said the group told the father to leave and took turns raping the woman before the father returned with police. Two of the teenagers, a 15-year-old and a 14-year-old, were turned in to authorities by their parents. The two other teens, 15 and 17, were apprehended by police. On Saturday authorities released a surveillance video of the five suspects inside a deli before the attack.
