Detectives from the Sexual Crimes Squad have issued further charges in relation to their investigation into reported sexual assaults dating back almost 30 years.
A 68-year-old Keysborough man was charged on 16 August with sexual penetration of a child under 16 years and indecent act with a child under 16.
The 13 charges relate to three complainants and are alleged to have occurred between 1996 and 2004.
Last week he was issued with a further seven charges in relation to a further two complainants who came forward following recent media reporting.
Police will allege the man came into contact with the complainants through his role at a Keysborough temple.
The investigation remains ongoing.
Victoria Police encourages all victims of sexual assault and child abuse, and anyone who has knowledge of such a crime, to make a report.
Victoria Police is committed to investigating and bringing to justice those people who prey on children no matter how many years have passed.
