This Atlanta Airport employee was begging Pacman to hit him! TMZ obtained video showing the NFL star retaliate violently after he was attacked by an airport employee.
Cops told us the altercation began when the ABM employee -- Frank Ragin -- made a gesture toward the NFL star as he was walking through the airport with a female companion.
You can see in the video ... Pacman (real name Adam Jones) calls out the guy and confronts him.
Ragin -- still wearing his orange airport vest -- goes after Jones, initiating the fight.
Jones tries to take off his backpack, but instead throws a haymaker at Ragin. The two exchange shots until Pacman lands the knockdown blow with an overhand right, sending Ragin to the floor.
Police were called and the employee was arrested for instigating the fight.
