"We have scoured over 400 villages and all possible forest land, where we think Jai could be, since his last known whereabouts on April 18," wildlife warden Rohit Karu told PTI over phone from Umred.
Asked if Jai could have fallen prey to poachers, Karu said that possibility was remote.
"He came to the sanctuary after traversing large tracts of land. He could be anywhere," Karu said.
Another forest official, however, did not rule out the poaching angle.

Named after Bollywood superstar Amitabh Bachchan's character in the hit 1975 film "Sholay", Jai was in limelight three years ago after embarking on an epic hike through villages, rivers and perilously dangerous highways in successful pursuit of a mate.
Jai has been a firm favourite with tourists and conservationists alike. Wildlife officials have launched a search operation for the seven-year-old, 250 kg big cat.
So far, there is no substantial clue about the whereabouts of the tiger, whose electronic collar stopped transmitting his location in April.
