The Panthers have passed on the name of a player from another club to the NRL integrity unit in the belief that person may be responsible for the distribution of lewd footage involving Penrith players.
The Panthers have spoken to a number of their players, who have reason to believe it may be another NRL player from a rival club.
The club has since given that name to the NRL Integrity Unit for further investigation.
Tyrone May, who last week featured in a video that was distributed on social media, met with the integrity unit alongside Panthers general manager of football Phil Gould on Sunday.
Two other Panthers players – one of whom is in the club's top 30, also met with the Integrity Unit on Monday after two more videos surfaced.
It is believed the player who Penrith suspect of distributing the videos has been asked to meet with the integrity unit on Tuesday.
Penrith are bracing for even more footage to surface in the coming days.
Earlier on Monday, Penrith winger Josh Mansour took aim at those behind the sharing of the videos.
Mansour didn't shy away from the fact players were damaging the game's brand as more videos surfaced, but also questioned those in possession of the footage.
"The players have got to take responsibility for having the videos in the first place and recording them," Mansour said during a school visit in Sydney’s west on Monday.
"In saying that I'm worried about what this is going to cause because generally the people leaking the videos, it's just not right. They're pretty much ruining people's lives for no financial gain, just for the sake of it.
"What have they got to gain? I think that's the most disappointing thing out of it."
Mansour is prolific on several social media platforms but is even beginning to question sharing basic aspects of his private life to the public.
The 28-year-old said he felt for his teammate May, who is a close friend, and felt the footage did not truly reflect him as a person.
"I’ve checked up on him, he's one of my good mates and a teammate of mine," Mansour said.
"I know him very well and he'd be hurting a lot now.
"Everyone's got their different views. I've grown up with two sisters and a single mum, my views with women are extremely high and I've got a daughter of my own.
"It's a scary time. It shouldn't be shared in the first place, without a doubt 100%. And that's the issue we have right now."
