A Florida man was charged with attacking his adult son with a machete after the son reportedly criticized the man for dating a much younger woman.

The Pasco County Sheriff's Office reports that 53-year-old Jeffrey Joseph Kolba and his 22-year-old son were arguing early Sunday morning when Kolba left the room and came back with a machete. Kolba reportedly hit his son on the left arm, leaving a 4-inch gash.

The son initially told deputies that he was jumped by five men. He later said he made up the story because he didn't want his dad to get in arrested.

Kolba reportedly admitted arguing with his son but said it did not become physical.

Kolba was charged with aggravated battery with a deadly weapon. He was being held without bail.
