The theme of the ad was to show a cricket match win. They had all necessary permissions," Kawale said.Conclusion: A video of a web series being shot has gone viral on social media with the misleading claim that it shows Bangladeshi nationals protesting in Mumbai's Virar.Old Video Falsely Shared as One Showing the Allegedly Hijacked Flydubai Flight(Not convinced of a post or information you came across online and want it verified?
