Photographer Tony Echevarria, 50, says that heavyweight boxing champion Mike Tyson struck him once at the Los Angeles airport in a scuffle that ended with both men being booked and released on suspicion of misdemeanor battery Wednesday. Echevarria went down after the strike, and a hospital treated him for a cut to the forehead. Tyson alleged through a spokeswoman that the photographer behaved aggressively and attacked him while he was traveling with his wife and 10-month-old child. His spokeswoman said Tyson "acted in self defense as a father protecting his child." Some eyewitness accounts back each of the versions. Both men have said they intend to press charges of misdemeanor battery against each other.
