National Investigation Agency officer Tanzil Ahmed is likely to have been killed over a personal grouse -- one of the killers was unhappy as he did not get help from the officer regarding a case, the Bareilly police said today.


The police have arrested two men in the case -- both aged between 20 and 25 years -- but the main accused is still on the run.


Ahmed was shot dead on April 3 by two men on a bike as he was on way home in Uttar Pradesh's Shahaspur after attending a wedding. His wife, who was with him, was injured and is still fighting for life.The police said one of the arrested men, Reyaan, was driving the bike. His accomplice, Muneer, who fired the shots, is yet to be arrested. The police have announced an award of Rs 50,000 for information on him.


"During interrogation, it was revealed that Reyaan had sought help from Tanzeel ji in a case. But he was frustrated as the officer denied help," said Vijay Meena, Inspector General, Bareilly.
