Two women who had just rented an apartment in Franklin Square Sunday discovered digital spy cameras hidden in smoke alarms in their bedrooms, police said.

The landlord, Michael Muratore, 44, who lives on the first floor of the 849 Second Ave. home, was arrested and charged with unlawful surveillance.

The women were moving into the second-floor apartment and decided to have the smoke alarms checked to make sure they were in working order -- and that's when the cameras were found, at around 5 p.m. Sunday, Nassau police said.

Fifth Squad detectives arrested Muratore in front of his home at 6:40 p.m. Monday. He faces arraignment Tuesday in First District Court, Hempstead.
