He is being held at the Suffolk County jail in Riverhead on a bail of $32,000, police said.

On July 12, police said, Liguori, a self-described artist and photographer, photographed the models at an Elm Street, Southampton, address.

"Mr. Liguori is alleged to have placed a live video camera in the female dressing room where the female swimsuit models were to disrobe," Lamison said in the release.

According to the New York State Division of Criminal Justice Services, Liguori is registered as a level 2 sex offender and was convicted in 2000 of disseminating indecent material to a minor.
