What initially began as an apparently genuine love affair turned into the accused woman gradually asking for money from the victim, which the police said he regularly transferred into her account over the years.According to the police, the relationship turned sour when the victim allegedly stopped sending Mehajabeen money every month, prompting her to allegedly plot his murder.She was allegedly aided in the crime by her husband, Hasan Sheikh, her brother, Tariq Sheikh, and the latter’s friend, Mojjam Pathan.How it unfoldedThe police investigation has so far revealed that the victim went to Mumbai's Dadar area on April 3 to collect cash for his company but never returned home.

When nothing was found, her three male accomplices tied up the victim’s hands and legs and assaulted him with plastic pipes.The assault allegedly caused head injuries, which in turn caused the victim’s death.The accused allegedly stuffed Khan’s body into a green drum and dumped it in a drain in an isolated area under the Valiv police station limits.Case filed and arrests madePolice arrested the accused woman, Mehajabeen Khatun Ekran Sheikh, and her brother, Tariq, on May 7.
