Richard Levis, 48, who lives in Butler, was arrested after an investigation by Oakland police and members of Acting Bergen County Prosecutor Dennis Calo's Confidential Investigations Unit.

Levis remained free pending a Jan. 23 first appearance in Central Judicial Processing Court in Hackensack, the prosecutor said.
