Priest charged 27 years after incident

A 58-year-old Catholic priest has been charged over an indecent assault at a NSW school nearly three decades ago.

Police allege the then chaplain indecently assaulted a 15-year-old boy at the school in Wollongong's north in 1988.

The charge comes four years after the matter was reported to police.

The priest was arrested on Monday afternoon and charged with one count of indecent assault.

He was granted conditional bail and will appear at Port Kembla Local Court on March 25.
