An angry Deltona father whacked his teenage daughter’s boyfriend with a metal pipe after finding the boy naked in his daughter’s room. Authorities say the father, 45, didn’t even know his daughter had a boyfriend or that the youngster had been sneaking into the home for more than a year.

When he heard noises coming from his daughter’s bedroom Thursday morning and saw a stranger standing naked on the girl’s bed, he swung a metal pipe. He then chased the teen out the front door and called police.

The boy was taken to the hospital where doctors closed a head wound with staples.

The father was charged with aggravated battery on a child and bonded out on $10,000.
