Another video showed someone grabbing a bus stop sign and swinging it at people. Rowdy fans were seen trying to climb an NYPD truck carrying barricades. 

The watch party was held at Bryant Park after the city, the NYPD and the Secret Service made the decision not to permit one outside Madison Square Garden.

There was high security outside the Garden and in Midtown Manhattan as President Trump attended the game. 

NYPD Commissioner Jessica Tisch said fans can expect a watch party outside the arena for Game 4 on Wednesday.
