The paparazzo told police that Tyson struck him once, airport police spokesman Sgt. Jim Holcomb said. The photographer fell to the ground and was treated for a cut to his forehead at a hospital.
Tyson's spokeswoman Tammy Brook said the boxer was traveling with his wife and 10-month-old child Wednesday afternoon when he was attacked by an overly aggressive paparazzi. He acted in self-defense to protect his child, she said.
Tyson and the unnamed photographer both want to press charges for misdemeanor battery, police said.
"There's a lot of different versions to this story and that's all going to come out later," Holcomb said. "There were numerous witnesses and that's what this whole case is going to depend on."
Tyson was being held at the airport police station and will be booked and released later, Holcomb said.
"Right now he is very compliant, very cooperative. He's just waiting in one of our holding cells," he said.
The photographer will also be booked once he is released from the hospital, police said.
