Kumar said victims consumed liquor during two customary functions on Thursday night, adding that the post-mortem and initial forensic reports suggested that the brew was laced with methanol.
Police have arrested eight suspected bootleggers while the provincial governments have suspended 35 officials including 12 police.
Deaths from illegally brewed alcohol are common in India because the poor cannot afford licensed brands. Illicit liquor is cheap and often spiked with chemicals such as pesticides to increase potency.
Illicit liquor has also become a hugely profitable industry across India where bootleggers pay no taxes and sell enormous quantities of their product to poor at a cheap rate.
