A violinist in the Colorado Symphony Orchestra has admitted to improperly touching two of his daughter's friends during sleepovers at his home, reports the Denver Post.

David Waldman was sentenced to ten years to life on an intensive supervision probation programme for sex offenders after pleading guilty to sexual assault on a child and attempted sexual assault on a child.

Waldman joined the Colorado Symphony in 1994 and holds the fourth chair position. He has also played with the Colorado Chamber Players and has worked as a mentor for the Denver Young Artists Orchestra.

Waldman is currently on unpaid leave with the orchestra. A decision regarding his future employment is imminent.
