The NYPD's Internal Affairs Bureau has launched investigation into whether cops used an illegal chokehold while making another arrest.
The suspect in this video has been identified as 23-year-old Ronald Johns.
He was arrested for allegedly fare beating in the subway.
When he refused to put his hands behind his back, officers seem to put him in a chokehold.
This all came to light during the Eric Garner investigation.
He was laid to rest tonight on Staten Island after dying while in police custody.
