TMZ Sports has obtained the witness statement in the Charles Oakley incident at MSG -- in which Knicks staffers claimed Oakley went on a verbal tear trashing white people, cops and Jimmy Dolan after things got physical with security.
According to the documents, one security guard told MSG investigators Oakley was talking to fans before the incident when he saw security looking at him.
The security guard says Oakley said, "You got all these f**king security here looking at me, I don't know what the f**k they're looking at, but they're getting on my f**king nerves.
