Tigress Avni, who is believed to be responsible for the deaths of 13 people in the past two years, was killed in Maharashtra's Yavatmal on Friday as part of an operation.
Fadnavis said preliminary reports made available to him stated that the tigress was shot after she attacked the forest staff trying to tranquilise her.
The committee said there was no operational coordination among veterinary professionals and the team which killed the tigress on November 2 in Yavatmal and that the dart for tranquillising the feline was fired unauthorisedly.
