Lucknow: Several people have been questioned in connection with the killing of National Investigation Agency (NIA) officer Tanzil Ahmed but no arrest or detention has been made so far, police said on Thursday.
"We are quizzing a number of persons, but there is no detention or arrest so far. If there is something concrete, we will share it with media," Additional Director General of Police (Law and order) Daljeet Singh Chaudhary told PTI here.
Chaudhary was replying to some media reports claiming that a relative of the slain NIA officer had been detained.
Tanzil Ahmed, probing terror cases related to Indian Mujahideen, was shot dead on April 3 by two unidentified motorcycle-borne assailants who also wounded his wife when they were returning home from a wedding near UP's Bijnor town.
The ADG had yesterday said some "personal matter" may have been the reason behind the killing and hoped to crack the case at the earliest after zeroing in on certain links.
"We are gradually zeroing in on certain links, especially some personal matters and are assessing forensic evidences. There are certain things which are indicating towards a personal matter," Chaudhary had said.
The police is also looking into any terror angle and a senior level Anti-Terror Squad (ATS) team with the help of other agencies is working on the case, Chaudhary said.
Meanwhile, data of the officer's mobile phone, which was damaged in firing, was being examined.
