IPL chairman Arun Dhumal confirmed that the ACSU had submitted a report to the BCCI regarding the issue.

“The Anti-Corruption and Security Unit has flagged certain anomalies and submitted a report about unauthorised persons being seen in dugout, team bus and team hotel during IPL matches,” Dhumal told PTI. “There are certain protocols under PMOA that need to be followed and the BCCI will be telling the franchises to be mindful of the SOPs so that the sanctity of the tournament is restored.

“This time, we have observed various anomalies and irregularities in the conduct of certain franchises and players,” Saikia told ANI on Thursday. “So BCCI and IPL are preparing an advisory, and we are going to release that advisory because we have noticed that there are a lot of unauthorised persons who are moving along with the team members. And some people who are unauthorised are coming to the hotels and to the players’ rooms or the team officials’ room, which is totally against our anti-corruption protocols.

“We have also seen that certain team owners and officials are mingling with players in areas where it is not allowed. So there are certain protocols we have to follow, and we have seen there are some dilutions. We have taken this very seriously. We are issuing an advisory, and it will be very strictly followed. If there is any violation hereinafter, then BCCI and IPL will take very stringent action.”
