The controversial video appears to show a man on the ground being held down by four police officers in an apparent chokehold.
"While a full investigation is still underway, there is no question in my mind that this immediate action is necessary," Commissioner Shea added.
Police say they were called to the boardwalk at 113th St. in Far Rockaway just before 9 a.m. Sunday after they say a man was harassing beachgoers and throwing things at them.
When police arrived, officers say he reached into a trash bin and threw something at them. Then, they say they placed him under arrest and he resisted arrest.
"One of the officers that was around him reached over and pulled him off," said Lori Zeno, Executive Director of Queens Defenders.
Zeno, the defense attorney of the man, says she wants answers.
Police later released bodycam footage of the arrest:
Dozens of protesters gathered outside the 100 Precinct on Sunday evening with signs and chants, demanding justice.
The NYPD released a statement saying, "We are aware of the video and there is an active investigation underway by the Internal Affairs Bureau. This matter is taken extremely seriously and we expect to have an update this evening as the investigation unfolds."
The man, identified by his attorney as 'Ricky,' appeared to be unconscious, but afterhe was handcuffed, he was seen walking and talking. His attorney also said he has bruises all over his arms and a large bump on his head.
He will face charges, but the charges have yet to be announced.
