One tiger, prowling in Rehman Khera on the outskirts of Lucknow since the past four months, is not only causing a major strain on the state exchequer but is also posing a major problem for the state government.

A sum of nearly `4 lakhs has been spent on the on-going campaign to nab the wild cat and forest officials have been camping in the area since early January — when the animal was first sighted — but all their efforts to catch him have proved futile.
