The incident came about while prankster Alexander Bok was carrying out a dare issued by daytime talk show host and comedian Ellen DeGeneres, who challenged viewers to "sneak up behind perfect strangers" and "dance behind them without them knowing it."
Bok danced behind unsuspecting New Yorkers in and around Grand Central Terminal in the video, which was reportedly filmed on Dec. 24.
Bok started performing the "Gangnam Style" dance behind an NYPD officer but stopped when the cop noticed him and turned around. At that point several cops could be heard questioning Bok while he tried to explain that he was just dancing.
"What's wrong with you, bro?" one of the cops could be heard saying in the video.
"What are you dancing in the street for?" another asked.
"Are you a fucking asshole?" another cop could be heard saying.
The verbal questioning eventually got physical and ended when one of the police officers pushed Bok to the pavement. _ This incident came amid particularly high tensions between police officers and citizens after a white police officer was not charged in the chokehold death of a black Staten Island man. Ongoing protests and unrest were further compounded after two NYPD officers were gunned down in an ambush attack on Dec. 20 in Brooklyn.
