Cops in Indiana are hunting for a creep who allegedly broke into the bedroom of a teenage girl in the middle of the night and was spotted on a neighbor’s security camera masturbating while watching two teen sisters get ready for school.

Nydia Botero, of Plainfield, said she and her husband had an argument last week over who moved a ladder in the back yard of their Emery Drive home, blocking access to the family’s doggie door. But when the couple reviewed footage from a home security camera, they saw a man pleasuring himself in their back yard at about 5:30 a.m. Aug. 19 — while peeping in the window as the couple’s teenage daughters were getting dressed for school, she told WTHR.

“He doesn’t care that we have a camera,” Botero told the station. “He doesn’t care we have neighbors. He doesn’t care if we have dogs. He’s just taking care of his business.”

The man — who tried to move the ladder against the home, but instead climbed a tree to get a better view inside the room — then stared into the family’s home via a back patio window before covering his face with his T-shirt when he noticed the security camera.

Police confirmed to the station that they were investigating the sick incident — which happened just before a woman who lives across the street reported being awakened Wednesday by the screams of her teenage daughter and nieces after they found a man in their bedroom.

“Their faces, they looked so terrified,” Bekezela Mguquka told the local NBC affiliate.

Mguquka said the girls told her that the man was crawling along the floor and watching them.

“He didn’t say anything,” Mguquka said. “Just staring at them.”

Mququka said it was the second time in three weeks that the girls said the man had sneaked into the room. In both cases, the suspect ran out of the home when the girls woke up and screamed. He likely gained access to the home by cutting window screens, WTHR reports.

“It’s so shocking,” Mguquka said.
