Kangaroos coach Mal Meninga says the fan who racially abused Greg Inglis at Panthers Stadium on Saturday should be banned for life.
Inglis was hit with a racial slur as he came from the field during the Penrith win. The centre was allegedly called a "black dog" as he was replaced.
Australia boss Meninga has called for the member of the crowd responsible for the abuse to be given a life ban by the NRL.
"I reckon Greg will be hurting, and I applaud him for his actions," he told Channel 7.
"Hopefully they find the perpetrator and kick him out for life. I thought that racial vilification has gone out of game, obviously it hasn’t."
The Panthers are working with the NRL to investigate the find the culprit.
"Panthers has been made aware of an allegation of racial abuse directed at South Sydney player Greg Inglis by a member of the crowd at Panthers Stadium yesterday,” Panthers CEO Brian Fletcher said in a statement.
"I wish to make it clear our club does not tolerate this kind of behaviour in any form. We will work with the NRL to investigate the matter and any perpetrators will be swiftly dealt with. Our club apologises unreservedly to Greg Inglis for the upset caused by the alleged incident.”
