At least 34 people have died and dozens hospitalized after drinking illegally brewed liquor in the southern Indian state of Tamil Nadu, local media reported on Thursday.

The state's chief minister M K Stalin said the 34 died after consuming liquor that was tainted with methanol, according to the Press Trust of India news agency.

The incident occurred in the state's Kallakurichi district, where more than 100 people are being treated in various hospitals, top district official M S Prasanth said. He added that the number of those who are in critical condition keeps changing, suggesting that the death toll could rise.

Ambulances, doctors and specialists from nearby areas were deployed to the district.

Government officials earlier said several people who were vomiting and had stomach pain were admitted to hospitals Wednesday, triggering a police investigation.

Later that day, Stalin, the chief minister, said in a post on social media platform X that those involved in the crime have been arrested, and action has also been taken against officials who failed to prevent it. “Such crimes that ruin the society will be suppressed with an iron fist,” he added.

Deaths from illegally brewed alcohol are common in India, where the poor cannot afford licensed brands from government-run shops. The illicit liquor, which is often spiked with chemicals such as pesticides to increase potency, has also become a hugely profitable industry as bootleggers pay no taxes and sell enormous quantities of their product to the poor at a cheap rate.
