A Rockland County gymnastics coach who is already serving time for molesting underage girls he taught is facing new charges.

The Rockland County District Attorney's Office says 71-year-old Joseph Lewin, of Hillburn, is charged with one count of sexual conduct against a child.

Lewin is accused of abusing a girl under 13 years old while serving as a gymnastics coach at his gym between 2012 and 2015.

As News 12 previously reported, Lewin was sentenced to prison after admitting to molesting at least seven girls between 2007 and 2014.

The DA is asking anyone who may have been victimized by Lewin to call them at 845-364-2800.
