EDISON - Police say they have arrested a Union County man on charges of child endangerment after he allegedly sent sexual messages on Facebook to a 15-year-old boy.

According to police, Frednel Lambert, 34, a church choir director, asked the boy about various body parts and personal habits, including relations with girls.

Officials say they are investigating to see if there were any other victims, either through Lambert's church work or his job as an adoption specialist for the state.
