The 38-year-old was reported to have been caught red-handed by the teenager’s stepfather who was checking up on his stepdaughter who was unwell.
He then called the cops in North Port, Florida, to report the under-age affair.
Local WINK News reports Lauren Debenedetta – who worked at Haven Dance Studio – was arrested on Monday for allegedly molesting the 15-year-old girl.
The police station said the teenager’s stepfather found Debenedetta with the underage student at the girl’s home.
He told detectives he had stopped off to check on her since she was meant to be at home sick for the day.
The teacher says she yelled at him to close the door and he went and called the girl’s mother to tell her what was happening.
