A tiger was found dead in the buffer zone of Tadoba-Andhari Tiger Reserve (TATR) in the district last evening.
The highly decomposed carcass was found in Warvat sub-range by a forest official, an official release said.
Deputy Director of TATR (Buffer) Gajendra Narwane and other officials rushed to the spot after getting the information.
Autopsy showed that one of its canines was broken and others were worn out. There was also an injury on its neck.
The aged tiger may have been mauled in a territorial fight with another tiger, officials said.
All body parts were intact, ruling out possibility of killing by poachers.
This is the fourth tiger death in TATR this year.
