Mumbai, 22/11: Byju Raveendran, the founder of Indian tech firm Byju’s, tried to convince a Nebraska businessman to leave the US in order to avoid testifying in federal court about suspicious activities he observed while working with the controversial executive the businessman told a judge during a court hearing Thursday. The businessman, William R. Hailer, said Raveendran sent him a plane ticket to Dubai just two days before Hailer was set to testify about Raveedran’s efforts to regain control of parts of the Byju’s education empire that had been taken over by a court-authorized trustee. A copy of the ticket, which cost nearly $10,700, was shown in court Thursday.
