At least 37 people have died from adulterated alcohol in the eastern Indian state of Bihar.
"More than two dozen people have lost their lives in the past 48 hours," a police officer said Saturday.
A total of 37 fatalities have been reported so far.
The official could not confirm reports that there should be more than 70 dead.
Relatives of the victims said residents of various villages drank a locally brewed liquor known as "Mahua" or "Desi Daru" at a wedding and other celebrations Monday.
After that, many complained of abdominal pain and loss of vision and vomited.
According to the information, more than 20 people died by Thursday, and about a dozen were in the hospital on Saturday.
Alcohol consumption is banned in the state of Bihar, leading to a thriving black market in homemade and sometimes deadly liquor.
In the past few days, the police arrested more than a hundred people in connection with the illegal production of alcohol, and 600 liters of adulterated alcohol were confiscated.
Authorities use drones, helicopters and motor boats to combat black market trafficking.
Hundreds of people die every year in India as a result of drinking contaminated alcohol.
