Suvendu aide's murder: Probe hinges on links with UP and UPI

Four days after the killing, police say no arrests have been made, though some suspects have been detained. Investigators are tracking a UPI payment linked to the Nissan Micra used to intercept Rath's SUV at a Bally toll booth. The SIT traced the car to a Siliguri resident and travelled to Uttar Pradesh in connection with the inquiry.

Why It Matters
