A Camden County man was arrested when he came here to meet a person who he thought was a 14-year-old boy for a sexual encounter, Atlantic County Prosecutor Jeffrey S. Blitz said Wednesday. The “child” was an undercover investigator.

Anthony Mastrando, 48, a postal carrier from Covington Drive in the Sicklerville section of Winslow Township, was charged with attempting to lure a minor to sexually assault the child and attempted sexual assault, Blitz said.

Mastrando, who is involved with youth groups at Covenant House and his church in Sicklerville, is being held in the Atlantic County jail on $100,000 cash bond, no 10 percent, Blitz said. Superior Court Judge Bernard DeLury made a condition of bail that Mastrando have no contact with children under the age of 18.
