"I would like to wish everyone a happy new year," Wankhede said. During Aryan Khan case, he was given four month extension which ended on December 31. Now, the Union Home Ministry will decide whether Wankhede will get a further extension or not. So far, no orders have been issued, and he will continue by default. A section of people have sought Wankhede be given another extension. The charge sheet in Aryan Khan case is yet to be filed before the Mumbai court.
