Newcastle's head of football Peter Parr has conceded the club's off-field issues are "self-inflicted" and indicative of a "lack of leadership" in the playing group after a video emerged of co-captain Kalyn Ponga and Kurt Mann being escorted out of a toilet cubicle by security.
The Knights told AAP they were made aware of the Snapchat video on Sunday night and on Monday, the club began an investigation that has now been handed over to the NRL integrity unit.
