Police launched investigations and arrested six people after 51 people were taken to hospitals in the state’s Ahmedabad and Butad districts on Monday, in addition to the deaths.
“Last night some people who were brought in hospital died and they were in serious conditions, “police officer Ashok Kumar Yadav told Reuters.
“They drank methyl alcohol, which was almost undiluted, thinking it was an alcoholic drink,” he added.
The sale and consumption of alcohol is prohibited in Prime Minister Narendra Modi’s home state, where only those with official government permission can drink.
Deaths from illegally produced liquor are common in India, where few drinkers have the ability to purchase branded drinks.
Methyl alcohol, also known as wood alcohol, is not suitable for human use and is mainly used as a thinner in paints or as a fuel.
