Balkar Singh got married to Rajwinder Kaur around 18 years ago and a few months back they had a tiff leading to which Kaur came to her parent's house, police said.
Yesterday, Singh went to his in-laws house in an inebriated condition and started hurling abuses on them, said Harvinder Singh Sandhu, Superintendent of Police.
In a fit of rage, Singh's wife, her sister and their two brothers allegedly tied him with an electric pole and thrashed him severely, the SP said.
A case against the four persons has been registered, the officer said, adding that they are absconding.
