7:31 PM PT -- NYPD officials tell TMZ Sports Oakley was arrested on 3 counts of misdemeanor assault. He is still in police custody.
Charles Oakley got into an ugly altercation in the stands during the first quarter of Wednesday night's Knicks game, and struck 2 security staffers ... one of them in the face, apparently.
The Knicks legend was hauled out and eventually arrested by NYPD ... according to the Knicks. It's unclear what started the melee, but the team says Oak "behaved in a highly inappropriate and completely abusive manner."
In video, he clearly gives one guy 2 HARD shots to the chest, and seems to slap another in the face.
Cops say Oakley's still in custody, but they don't have charges yet.
