Wagga police have appealed for information relating to child sex offences allegedly committed between 2000 and 2002.
Riverina Police District Detective Inspector Phil Malligan said on Tuesday that one man has been charged and there may be further arrests over "historic sexual assaults" in the in the Tarcutta and Humula area.
"We have charged a 68-year-old Mangoplah man in respect to some child sex offences that occurred in the Tarcutta-Humula area in that era, between 2000 and 2002," he said.
"We are currently looking for assistance from the public who may have some information that could assist investigators in terms of this particular offence as well as potentially other offences that may have gone unreported.
"Any information from any of the people who may have lived in that area in that time, would certainly be important to investigators."
The 68-year-old was charged on Wednesday last week and has been released on bail.
Detective Inspector Malligan did not reveal any details about the victim or victims in the case other than to state they were children at the time of the offending.
"Anyone that is still living in (the Tarcutta-Humula area) that may have had (child) family members at that time, may have some information that may help Wagga police," Detective Inspector Malligan said.
"I am not going to speculate on any further offenders, but certainly we feel there is information from the residents in that area at that time that may be able to assist investigators, and this may lead to further arrests."
