Further abuse charges for NSW deputy head

A deputy principal at a private high school in NSW's south has been slapped with three extra charges relating to the indecent assault of female students.

Police were investigating the assault of a 14-year-old girl last month, when they uncovered more alleged indecent assaults of three other girls from the same school.

The 50-year-old deputy principal allegedly assaulted two 14-year-olds and a 15-year-old during a school camp in Victoria.

Child Abuse Squad detectives have charged the man with three counts of aggravated indecent assault.

He was granted conditional bail to appear before Deniliquin Local Court on July 21.
