Police arrested an East Patchogue landlord Wednesday night and accused him of using hidden cameras to spy on a 16-year-old tenant.

According to investigators, Louis Bosco's surveillance system was uncovered by the victim when she saw her room displayed on a monitor in the landlord's house. Police say she later found cameras in her bedroom and bathroom.

The girls' father, Robert Hayducka, is outraged over the allegations.

"We trusted him," says Hayducka. "We let him in our house, we ate with him, we treated him like family and this is what he did to us."

Bosco, 44, is being charged with unlawful surveillance. The Suffolk County District Attorney's Office says if convicted, Bosco faces up to four years in prison and possibly a $5,000 fine.
