Lucknow: An officer of the National Investigation Agency (NIA) was shot dead by the unknown assailants while he was returning from a wedding in Uttar Pradesh's Bijnor district after midnight on Saturday.
Tanzil Ahmad, 48, known for undercover operations, joined the NIA in 2010.
The shooting in Bijnor district took place when the officer, an assistant commandant in the Border Security Force (BSF) and on deputation with the NIA as an inspector since 2010, was returning from a wedding with his wife and children. His wife Farzana received four bullet injuries, but his children were unharmed.
His wife is undergoing treatment at Fortis Hospital in Noida.
The officer was laid to rest with full state honours in Shaheen Bagh area of south Delhi.
"Tanzil Ahmed was an asset to the agency. His killing is a great loss to NIA. We take it as a challenge to bring the perpetrators of this crime to justice. We will not rest until that happens," NIA said in a statement.
The Uttar Pradesh police said they were working "on all angles" to find out the motive behind the killing of Ahmad. "Nothing can be ruled out now until and unless we get absolute concrete evidence. We have to work on all angles. We have to see it from all the sides and work out the case," Daljit Chowdhary, additional director general of police, Uttar Pradesh, said on Sunday.
He said borders have been sealed, nearby areas are being searched and senior officials from Anti-Terrorist Squad (ATS) have been put on the job to track the assailants and probe the attack.
Meanwhile, NIA termed Ahmad's killing a "planned attack".
"A planned attack took place on him when he was fired upon and killed," NIA spokesman Kumar said. "He (Tanzil) was assistant commandant with BSF and currently on deputation with NIA. He was with us for last six and half years."
