Cricketer Suresh Raina was questioned by the Enforcement Directorate on Wednesday over his endorsement - he is reportedly the brand ambassador - of 1xBet, an illegal online betting app. The ED is investigating money laundering charges against several such apps - including Lotus65 and FairPlay, and associated betting platforms like 1xBet - and has expanded inquiries to include celebrities, like Mr Raina and Bollywood actor Urvashi Rautela, who endorse them.
