The deaths occurred in the Indian state of Bihar, where alcohol is banned.
Homemade liquor has poisoned at least 27 people to death in India, local authorities tell the news agency AFP.
There have been deaths since Saturday in the state of Bihar in eastern India.
Alcohol is prohibited in that state, which has led to the production of pontika and a large-scale black market trade. According to the preliminary investigation, the lethal injection contained methanol.
The police have arrested 174 people in connection with the incident.
Every year, hundreds of Indians die after drinking toxic, home-made alcohol.
