Parveen Azad, wife of slain DSP Zia-ul-Haq on Thursday said that she was not "satisfied" with the CBI's supplementary chargesheet giving a clean chit to former UP Minister Raghuraj Pratap Singh and would appeal against it.
"I am not satisfied with the CBI report...My husband had been killed brutally and I want justice," Azad told reporters here.
"I will appeal against it," she added.
Azad said that she would not concede defeat without knowing the truth.
CBI on Thursday filed a supplementary chargesheet in connection with the murder of Kunda DSP Zia-ul Haq before a special court here in which it has given a clean chit to Raghuraj Pratap Singh alias Raja Bhaiya.
The agency also filed a "technical" closure report in the FIR filed by Haq's wife in which she had accused Raja Bhaiya of conspiring to murder the officer.
Raja Bhaiya, who was Food and Civil Supplies Minister, had to resign from the Cabinet on March 4 after Haq's wife had accused him of being involved in the DSP's murder.
