Wakefield fans on Saturday
The Rugby Football League will investigate alleged racial chanting during the Super 8s Qualifiers match between Wakefield and Bradford at Belle Vue last Saturday.
The Wildcats announced earlier this week they were looking into "misconduct and unacceptable behaviour of spectators" and now the governing body is to probe a number of incidents after receiving a report from its match commissioner.
An RFL spokesman confirmed an investigation has begun.
Wakefield chairman Michael Carter said his club would work with their stewarding company, West Yorkshire Police and the RFL to identify the perpetrators and ban them for life.
Carter said: "We have received reports of alleged disorder during the game on Saturday. As a club we will not tolerate such things and will cooperate fully with any investigation.
"It is extremely sad in this day and age that a small minority can tarnish the event."
Earlier this year, Wakefield were fined £1,000 after fans threw smoke bombs on to the pitch during their opening match of the season at Castleford.
