Former world heavyweight boxing champ Mike Tyson has been arrested after a paparazzi photographer was reportedly punched in the face at LAX international airport.

He is reported to have been "released on his own recognizance" after being charged with misdemeanor battery - with bail set at $20,000.

US gossip site TMZ reports that Tyson was waiting to check-in with United Airlines when he was approached by the snapper.

A witness claimed that the photographer got very close before Tyson punched him, causing him to fall to the floor - then leaving a trail of blood as he got up and walked away.

But TMZ also says the snapper was charged with misdemeanor battery too - and that both parties performed citizen's arrests on one another.

Hmmm.
