The National Investigation Agency (NIA) has arrested six people including a Khalistani ideologue Lucky Khokhar alias Denis, a close associate of Canada-based Khalistani terrorist Arshdeep Singh alias Arsh Dala. The arrests came after the NIA carried out raids at 76 locations in eight states on Tuesday to bust the nexus between criminal gangs, terror groups and drug mafia. Others arrested in the raids included associates of gangsters Lawrence Bishnoi, Jaggu Bhagwanpuria and Goldy Brar.
