Lucknow, Apr 13 (IANS): The Uttar Pradesh Police has announced a Rs.2 lakh reward on information about Muneer, the prime accused in the murder of NIA official Tanzeem Ahmad, an official said on Wednesday.

While two others involved in the killing -- Reyan and Jainul -- have been arrested, Muneer continues to be at large.

Director General of Police Javeed Ahmad had earlier announced a reward of Rs.50,000 on Muneer, a sharp shooter and named in many cases including a murderous attack on an AMU student and also in a bank robbery.

Hailing from Bijnor, Muneer has gone missing after the NIA official was killed more than a fortnight ago while returning with family from a wedding.

Police have since claimed to have cracked the case and inferred that the killing was a result of a simmering hostility between the killers and the deceased official and a property dispute over a shop in New Delhi.

Police,however, have failed to address missing links like conflicting reasons for the murder, non-recovery of the murder weapon and the vehicle used to flee the crime scene.

Inspector General (Bareilly) Vijay Kumar Meena, however, said many links which seemingly are missing so far will fall in place once Muneer is arrested.

He is feared to be hiding in either Mumbai or Goa. Since he does not use a mobile phone, tracking him down through cyber surveillance is impossible, an official conceded.
