Tea plantation workers torched the home of their boss, killing both him and his wife, following a labor dispute in the northeastern Indian state of Assam, officials said on Thursday.

Around 1,000 workers at the privately-owned M.K.B. Tea Estate attacked the plantation owner's bungalow on Wednesday and set it on fire in violence blamed on festering labor unrest in the tea-growing region, police said.

Mridul Bhattacharya and his wife Rita were burned to death as workers armed with home-made weapons prevented police from rescuing them.

"The body of the planter was charred beyond recognition and reduced to ashes while the body of the wife was found lying in the kitchen," local police officer A. Das told AFP by telephone.

The grisly attack occurred in Assam's tea-growing Tinsukia district, some 500 kilometers east of the city of Guwahati.

The Indian Express newspaper said the violence was sparked by orders served by Bhattacharya on 10 estate workers to vacate their quarters and the detention of three employees by police over unspecified disputes.

Assam produces around 55 percent of India's annual tea production, which stood at 988.32 million kilograms last year, and the state is home to more than 800 tea estates.
