At least 133 people have died and about 225 people have been hospitalized after drinking tainted liquor in two separate incidents in India's remote northeast, authorities said Sunday.

The victims of one of the deadliest bootleg liquor-related incidents in India were mostly tea plantation workers in Golaghat and Jorhat districts in Assam state, said top police official Mukesh Agarwal.

Assam is India's largest tea-producing state, with more than 1,000 plantations producing more than 50 percent of Indian tea.

The workers consumed the tainted liquor laced with methyl alcohol, a chemical that attacks the central nervous system, on Thursday and started falling unconscious. They were rushed to nearby hospitals and the death toll rose to 133 by late Saturday, police and health officials said.

imanta Biswa Sharma, Assam's health minister, said about 200 people who fell sick after drinking the toxic liquor are in hospitals, some in critical condition.

Manab Gohain, a doctor at the Jorhat Medical College Hospital, said 34 patients have died in the past 24 hours.

The owner of a local brewing unit and 13 others have been arrested, police official Agarwal said. Awarwal said police are pursuing other people believed to be connected to the racket as part of an ongoing investigation.

"We shall not spare anyone involved in manufacture and distribution of the tainted liquor," minister Sharma said.

Locals vandalized home of one of the arrested. Authorities collected samples for the medical tests.

Deaths from illegally brewed alcohol are common in India because the poor cannot afford licensed brands from government-run shops. Illicit liquor is cheap and often spiked to increase potency.

In India's Uttar Pradesh state earlier this month, about 80 people died from tainted bootleg liquor.
