The decision not to bring rape charges against the suspect may have set in motion a chain of events that allegedly led to another rape on the rooftop at 550 West 153rd Street.
Police say the same man raped another woman on the rooftop of the same five-story apartment building was a couple of months ago.
Investigators say the suspect is 25 year old Taurean Williams.
He was picked up while he was out on bail in connection with the rape of a 17 year old girl in October.
Francisco Gilbert he and others in the building live in fear.
"The people that live here, everybody is afraid. It's sad," he said.
The latest incident on New Year's Day hasn't helped. According to the NYPD, the suspect, while posing as an undercover cop, confronted a 45-year-woman on the street.
While flashing a shield and a gun, he told her she was under investigation and led her into the building and up to the rooftop where the rape occurred.
Why was the suspect out on bail? According to the police even though he was arrested in October on rape charges, he ended up pleading guilty to a lesser charge.
He was allowed to go free on 25-thousand dollars bail until sentencing later this month.
In the meantime, investigators say the suspect attacked someone at the same building again, perhaps because there are no locks on the doors to the entrance.
Residents say the locks were ripped out by same people who have allegedly harassed them for months.
