Gonda (UP), Dec 22 (PTI) Donating a kidney to her brother to save his life proved rather expensive for 42-year-old Tarannum as her husband divorced her by pronouncing 'talaq' thrice over a WhatsApp call after she refused to charge her brother, police said on Friday. Circle Officer (Sadar) Shilpa Verma on Friday said based on the complaint lodged by Tarannum, a case has been registered against her husband Mohammad Raseed at the Dhanepur police station here, and the matter is being investigated.
