Charges included assault on a police officer, criminal possession of a weapon, reckless endangerment, criminal mischief, disorderly conduct, resisting arrest, obstruction of governmental administration and trademark counterfeiting, police said.

The NYPD said 10 of its members were injured, including one who was struck in the head with a glass bottle.

“This is an exciting time for the Knicks and for fans across New York City,” the department said in a statement. “The NYPD wants New Yorkers to be able to enjoy these celebrations, but our primary responsibility is to ensure that everyone can do so safely.”

The celebrations came after the Knicks made a record comeback from 29 points down to defeat the Spurs 107-106, taking a 3-1 series lead.

On Monday, police took nearly two dozen people into custody outside a Knicks watch party at Bryant Park.
