8:22 AM PT -- The LAPD has updated number and it's worse than initially thought.
Now, cops say 76 people were arrested in total and 8 officers were injured in the Sunday night chaos.
The LAPD says 2 people were injured by "less lethal munitions fired by our officers."
Additionally, more than 30 buildings were damaged.
The LAPD issued a statement saying, "What started out as a largely peaceful celebration of the Los Angeles Lakers NBA championship in downtown Los Angeles, turned into confrontational, violent and destructive behavior late last night."
"A crowd of more than 1,000 revelers descended into the area around Staples Center after the game. Unruly individuals mixed within the crowd began throwing glass bottles, rocks, and other projectiles at officers."
"That is when an unlawful assembly was declared, and only a limited number of people complied and began to disperse. A larger portion of the group broke off and began vandalizing businesses while continuing to engage in violent behavior, some aimed at responding officers"
"In total, 76 individuals were arrested for Vandalism, Assault on a Police Officer, and Failure to Disperse."
Cops arrested 67 people outside Staples Center in L.A. Sunday night -- in a crazy celebration that had everything from fireworks to a guy in an actual plastic bubble!
Hundreds of fans gathered outside the arena -- despite the fact, the team was still in Orlando, Florida -- and things got crazy quickly!
So many people showed up (remember, we're still in a pandemic) -- that law enforcement declared an unlawful assembly in an effort to get people to go home!
The California Highway Patrol also shut down freeway off-ramps into the area to stop the crowd from growing in size.
Ultimately, we're told cops arrested 61 people for failing to disperse, 5 for looting and 1 for vandalism -- totaling 67.
We're told one police officer was injured in the chaos -- suffering a hand injury from a bottle somebody had thrown at cops.
Some fans were also injured. There are pics of paramedics treating someone outside Staples but unclear exactly what happened.
Not all of the fans were combative -- there were groups of people chanting Kobe Bryant's name, others waving Lakers flags.
But, there were times where fans got aggressive with police -- some even tried to kick in the windshield of a cop car -- which led to officers to brandish weapons in order to try and keep the peace.
We've seen footage from the celebration of fans fighting in the streets, looting a Starbucks and setting off fireworks.
