Tony Beckham, a former NFL defensive back, jumped into action when he discovered a peeping Tom outside his 15-year-old daughter's window.
Beckham, a former Detroit Lions and Tennessee Titans player, reportedly saw the suspect outside of his daughter's bedroom window, with his hands down his pants.
The incident occurred on Monday morning at Beckham's apartment in Palm Beach County, Florida.
According to TMZ, Beckham sprung into attack mode "when he saw the guy making masturbating motions" while his hands were inside his pants. Beckham said he was getting ready for work when he noticed a commotion outside the window of his home.
Beckham's wife, Amanda, called the police, but the former football player went on to chase the suspect — later identified as 48-year-old Geoffrey Cassidy — and broke the man's face in several places after tackling him in the apartment complex's parking lot.
Beckham, 40, told WPBF-TV that Cassidy was peering into the teen's room as she exited the shower. Cassidy's pants were reportedly undone.
Beckham held Cassidy until police arrived on the scene.
Police arrested Cassidy and booked him for lewd or lascivious exhibition in the presence of a child. If convicted, Cassidy could face up to 15 years in prison.
Cassidy denied any wrongdoing, and said that he was simply walking around the area after his vehicle had broken down.
