Penrith have hired cyber investigators to trace the source of false allegations about the club which have been circulating on social media.
The Panthers released a statement on Wednesday to say the club denies the allegations relating to "inappropriate relationships" between a former staff member and current staff.
"Panthers have been made aware of false allegations circulating on social media alleging inappropriate relationships between a former staff member and current staff members.
"The allegations are untrue. Panthers have instructed their lawyers and are also retaining cyber investigators to trace the source and sharing of the allegations and to apply the full force of the law including reporting the matter to the police.
"No further comments will be made until the investigations have concluded."
On the field, Penrith have enjoyed their best season since their 2003 title and wrapped up the minor premiership last Friday and finish their regular-season campaign on Saturday against Canterbury.
