Much of this alleged incident between these three openly gay men and police is caught on video.
And now it is being closely examined as part of this investigation.
At the same time, two of the men are speaking out for the first time.
"We did absolutely nothing wrong. What was done to us is wrong," said Josh Williams, an alleged victim.
Josh Williams and his friends Ben Collins and Antonio Maenza are now describing, in limited terms, what they claim was the wrong way they were treated by NYPD officers, who they also accuse of using anti-gay slurs during a confrontation.
The incident was caught in large measure on video outside the 79th precinct in Bedford-Stuyvesant in the early hours of Sunday, June 3, shows officers questioning Josh Williams, who they accuse of urinating on a dumpster in the parking lot.
"The officer responded by grabbing Josh. He thrashed Josh around and was then joined by other officers who slammed Josh to the ground and pepper sprayed him while he was on the ground in handcuffs," said Ben Collins, an alleged victim.
Police officials claim Josh Williams was combative, appeared to be intoxicated, and was resisting arrest as other officers moved in to place him in handcuffs.
Ben Collins says at one point, police used anti-gay slurs when they asked for the officers' identification.
Police claim two of the friends were trying to interfere with the arrest.
"Tony and I left to go home until officers came and chased after us and arrested us. Saying they will find something to charge us with," Collins said.
"I've seen the video and think it is appropriate to have it investigated by the Internal Affairs Bureau," Police Commissioner Ray Kelly said.
The video is being looked at closely and Commissioner Ray Kelly says the case is also being investigated by a civilian review board.
"Our concern is that this doesn't happen to anyone else and we want everyone to feel safe on the streets," Williams said.
The three men joined a number of people at a press conference condemning violence against the LGBT community.
Afterwards, they would not speak to reporters.
