The Enforcement Directorate has frozen bitcoins worth ₹12.83 crore in connection with an ongoing money laundering probe against Kolkata-based Aamir Khan, who launched the gaming application, 'E-Nuggets', and allegedly duped people. ED seized ₹17.32 crore in cash after raiding the premises of Khan and his father in Kolkata earlier this month. Khan was arrested from UP's Ghaziabad last week.
