Charles Oakley from downtown.

The former Knicks enforcer was arrested at the Cosmopolitan Hotel in Vegas last month for cheating, not once, but three separate times.

According to court documents obtained by TMZ, Oakley pulled a $100 chip back when he realized he would lose a hand, then added chips on two other hands to increase his winnings. Oakley was playing Ultimate Texas Hold’Em, where your hand gets matched against the dealer’s.

He was immediately arrested, as the casino says they saw the proof on their surveillance video.

Oakley was charged with misdemeanor disorderly conduct. He was initially charged with a felony that carried a six-year sentence, but it was reduced. Oakley is not expected to serve any prison time.
