Suffolk County Police arrested a landlord Wednesday who they say installed video and audio equipment to spy on a teenage girl at an East Patchogue home.

Police say Louis Bosco, 44, installed several hidden cameras and an audio device in the girl's bedroom and bathroom in the apartment, at 635 South Country Road.

Police described the devices as "pin cameras."

Bosco, who is described as a self-employed handyman, lives in a trailer next to the house.

According to the victim's mother, the teenage girl and her 8-year-old brother were walking outside their home and passed by Bosco's trailer and noticed a monitor inside, showing Bosco speaking to their mother inside their house.

The girl told her parents who then notified Suffolk County police, authorities say.

Bosco was arrested and charged with with second-degree unlawful surveillance.

The girl's mother, who did not want to be identified, said she is distraught over the situation.

"I feel guilty because I didn't know the video cameras were inside my home," she told PIX News. She adds that even though they removed all the cameras from her home she still feels like she is being watched.

Bosco was arraigned in First District Court in Central Islip on Thursday.
