READING, Pa. (AP) — A Pennsylvania father is apologizing after police say he pulled his daughter’s male friend by the hair and chopped off his dreadlocks with a knife.

Reginald Hardy was charged with aggravated assault, terroristic threats and other offenses after police say he saw the 19-year-old sneaking around his apartment Friday with his 17-year-old daughter.

Police say the 38-year-old Hardy punched the 19-year-old in the face and threatened to shoot him in the back if he ran away as he left.

Hardy said he was only looking out for his daughter. He says her friend was disrespectful to him and shouldn’t have been at the apartment.

Police say Hardy cooperated with the investigation. He’s free on $50,000 unsecured bail.

A preliminary hearing is scheduled for Jan. 12.
