The attack Thursday night, in which the police said five young men with a gun separated a father from his daughter and then took turns raping the 18-year-old woman, set off waves of anger and uncertainty in the Brownsville neighborhood where it happened. Elected officials also questioned whether the police notified the public quickly enough after the attack.
The two teenagers, a 15-year-old and a 14-year-old, were being questioned by the police a day after they released a surveillance video of the five suspects in a deli before the attack. The police said the young men ordered the father to leave, and then ran off before the father found help and returned with the police.
"It forces you to think differently about your own neighborhood," said Alethea Pierce, who has lived in the area for 43 years.
There remain many unanswered questions about the assault and its aftermath.
The police said five young men, one of them armed, walked up to the father and daughter in Osborn Playground just after 9 p.m. Thursday. The father and daughter told the police they had been at the playground drinking beer, a Police Department official said Sunday. That official and the law enforcement official spoke on the condition of anonymity to discuss a continuing investigation.
The father ran to get help, but the police official said it took him roughly 20 minutes to come upon two uniformed police officers on patrol. By the time the father returned to the playground with the officers, the young men had each raped the woman and fled, the official said.
In an area filled with public housing high-rises, delis and other stores, it is unclear why the father was not able to get help from bystanders or call the police from a store. The police said there was no evidence of any 911 calls being placed in connection with the attack.
The officers immediately called for an ambulance when they arrived, and the woman was taken to Kings County Hospital Center for treatment.
Without other witnesses, investigators on Friday began canvassing the area for video, starting with subway stations and businesses and expanding outward, the official said. They also conducted a second, more detailed interview with the woman.
On Saturday afternoon, investigators found a surveillance video that shows the young men walking into a nearby deli before the rape. The video was released with the public notice.
