A former Detroit Lions defensive back has made headlines after he beat up a man he said he found masturbating outside his daughter's window in Florida.

Tony Beckham told WPBF-TV in West Palm Beach that he found the man, leering into his 15-year-old daughter's room right after she had showered at 6:40 a.m. Monday with his pants undone and fondling himself.

That's when Beckham reacted.

First, he yelled at the man, who tried to run away.

After chasing down the man in the apartment complex's parking lot, Beckham said the two "had a good conversation."

That conversation resulted in several broken facial bones for Geoffrey Cassidy, 48.

Beckham, 40, was drafted in the fourth round of the 2002 draft by the Tennessee Titans. He was there until 2005. He played for the Lions in 2007, his final NFL season.

Beckham's wife, Amanda, told WPBF she called the police, who arrested Cassidy for lewd and lascivious behavior with a victim younger than 16 years old. He's being held in Palm Beach County Jail on a $1,500 bond.

Cassidy's mug shot shows plenty of evidence of his "good conversation."

WPLG-TV in Miami reports that first police took Cassidy to the hospital to treat the injuries. He reportedly denied the sexual act, saying he was in the neighborhood because his car broke down and he was waiting for it to cool.
