Farzana, wife of late NIA officer Mohammad Tanzil Ahmed, who was shot dead by assailants in Uttar Pradesh's Bijnor district, succumbed to her injuries in New Delhi on Wednesday.
Farzana had been referred to the AIIMS trauma centre from Noida's Fortis Hospital on Monday evening where she had been kept in ICU and was battling for her life.
Tanzil Ahmed, probing terror cases related to the Indian Mujahideen, was shot dead on April 3 by two unidentified motorcycle-borne assailants who also wounded Farzana, when they were returning home from a wedding.
The Uttar Pradesh Police yesterday said that “domestic dispute” had led to the killing of the NIA officer.
"All aspects, including professional, personal rivalry, were looked into during the probe. Terror angle was specifically investigated. Reyaan (accused) was in frustration because he was denied help from Tanzil Ahmed when he needed it," Inspector General (Bareilly Zone) Vijay Singh said.
Uttar Pradesh police has arrested two accused, Jainul and Reyaan, in connection with the case.
The state police had announced a reward of Rs. 50,000 to those providing information leading to the arrest of main accused Munir in connection with the murder of the NIA officer.
