Cameron Bancroft was ultimately tasked with carrying out the plan.Bancroft attempted to rough up the ball using yellow tape and dirt from the pitch. However, television cameras soon caught him working on the ball.The footage showed Bancroft appearing to realise that he had been spotted before putting the object down his trousers. When the umpires approached him, he produced what appeared to be a sunglasses pouch.The umpires inspected the ball but did not believe its condition had changed enough to warrant replacing it or awarding South Africa five penalty runs. However, the incident soon escalated beyond the field.Steve Smith, Bancroft admitted the planAfter play, Smith and Bancroft admitted that they had attempted to alter the ball. Smith said the plan had come from the team’s “leadership group” and accepted responsibility.Smith’s admission raised questions about who else knew about the plan and how extensively it had been discussed within the Australian camp.Also read: Steve Smith Adds New Layers To Sandpaper Gate ScandalCricket Australia’s subsequent investigation established that Warner had instructed Bancroft to carry out the plan using sandpaper.
