Penrith call in lawyers on false rumours

Penrith have called in lawyers to shut down vicious social media rumours circulating on the eve of the NRL finals.

The Panthers confirmed on Wednesday they had engaged cyber investigators after the rumour spread quickly on social media over the past weekend.

Several within the club are furious over the alleged actions of internet trolls, with messages being sent on several social media platforms since they won the minor premiership on Friday.

"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 club said in a statement.

"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."

The drama comes after Anthony Seibold also engaged lawyers and cyber investigators to look into scurrilous rumours when he left Brisbane.

Several names were passed onto the NRL's integrity unit, but so far no further action has been taken.
