Police in Piermont say a volunteer firefighter has been arrested for exposing himself to a teenage boy.

Michael Bettman and two underage teens were inside a Piermont firehouse a month ago when investigators say they exposed themselves and told a third teen, the alleged victim, to touch their genitals. The 29-year-old Bettman has been charged with endangering the welfare of a child.

Bettman and the two teens allegedly involved in the incident are expected to appear tomorrow in Piermont Village Court.
