A Rockland County gymnastics coach who already served time on child abuse charges has pleaded guilty to new charges.

According to a court website, 72-year-old Joseph Lewin admitted in Rockland County court to sexual conduct against a child.

Lewin was accused of sexually abusing a female under the age of 13 while serving as a gymnastic coach at his gym in Hillburn.He will be sentenced in February.

Lewin was released on parole last February, after having served 3 1/2 years in state prison for molesting a girl.

That plea covered sexual abuse against seven other girls, all of whom were students at his gyms in Suffern and Hillburn.
