In a ghastly act of avenging the insult they felt they were subjected to a few days ago, a quartet abducted a 45-year-old from her Vasai residence in the wee hours of Monday and raped the woman before murdering her.

The accused later dumped the body into a nearby nullah. Officials from Waliv police station said they arrested Shankar Chauhan, Mahesh Chauhan, Sangam Lal Kullu Morya and Shailendra Dubey on Tuesday.
