The animal was identified by Dr Reza Khan, principal wildlife specialist, Dubai Safari.
Zakir Hossain, a resident of Kamrabandha village said locals spotted the rare animal hanging by a bale (wood apple) tree, from which they rescued it.
Many people from other villages crowded the place to get a glimpse of the animal.
