India's Enforcement Directorate (ED) arrested a Kolkata-based businessman on Sunday and conducted searches at the residence of a senior city police officer as part of a money laundering investigation. The businessman, Kamdar, Managing Director of Sun Enterprise, was detained at his home and arrested under the Prevention of Money Laundering Act (PMLA) after questioning at the ED's office. Searches were also carried out against Kolkata Police Deputy Commissioner Shantanu Sinha Biswas, with investigators targeting what they describe as a criminal-linked syndicate in West Bengal, a state heading towards elections.
