Yunus Bepari, 46, an autorickshaw driver, went to a village fair last Monday with two wives where he was confronted by his third wife. When the women exchanged information, they found that he had a fourth wife too.
The three women learnt that Yunus' fourth wife was living in another village. The three women then took him to the residence of his fourth wife at Kabirpur where the four women together beat him up mercilessly, New Age newspaper reported, quoting local villagers.
He was taken in a critical condition to Faridpur Medical College Hospital where he died.
Islamic Shariah allows a man to take up to four wives, but that should be with the consent of his existing wives, the newspaper said.
