The Bengaluru Police have busted a major interstate racket selling fake Nandini ghee, arresting four men linked to a supply hub in Chamarajpet. Raids revealed over 8,000 litres of adulterated ghee, machinery, poor-grade palm and coconut oil, along with assets worth ₹1.26 crore. Samples are being tested to check if animal fat was used. A CCB-led probe is underway.
