Pune, May 30 -- At least 15 people have died and four others have been hospitalised across Pune and Pimpri Chinchwad in Maharashtra over the past 48 hours after they allegedly consumed spurious liquor, prompting a massive crackdown on illicit liquor network and the arrest of six people, police said on Friday. CM Devendra Fadnavis termed the incident "very serious", and said further action was being taken as the "entire ecosystem" involved in the supply of spurious liquor has been identified. The probe has since been transferred to the CID. The deaths have been reported from Phugewadi and Dapodi in Pimpri Chinchwad and Hadapsar in Pune city, where victims allegedly consumed country liquor, suspected to have been mixed with a toxic substance. Police said viscera samples of all the deceased have been sent for chemical analysis. However, people familiar with the matter said that the main accused, Yogesh Wankhede, had sourced methanol online and mixed it in country liquor to enhance its intoxicating content at a location near a toddy shop in Khadki a few days before the deaths were reported. According to officials, the adulterated liquor was then filled into 35 large cans and distributed to Phugewadi, Hadapsar, among other parts of Pune city....
