A 35-year-old Chartered Accountant has allegedly murdered 14 members of his family before hanging himself to death in Mumbai, India.

According to multiple reports, the man, who was identified as Hasnin Anwar Warekar killed seven of his nieces and nephew, his parents and other family members with a butcher’s knife before committing suicide.

“The attacker, Hasnin Anwar Warekar, hung himself after slitting the throats of all other family members including his parents,” a Thane police spokesman, Gajanan Laxman Kabdule, told AFP.

While investigation has commenced on the bizarre action by the late chartered accountant, the sole survivor of the attack, Warekar’s sister, was taken to hospital after neighbours heard her screaming for help after midnight and alerted police.

“We still haven’t been able to speak with the attacker’s 21-year-old sister, the lone survivor of the attack, who is in deep trauma at a city hospital,” Kabdule said.

According to the Press Trust of India news agency, a property dispute was allegedly responsible for the motive behind Wareka's killings.
