The committee would be headed by former PCCF Saroj Patnaik and would submit its report within a week, said Nandankanan director Sudarshan Panda.
The committee would look into whether there was any negligence on part of the Nandankanan authority in handling the giraffe after its arrival here.
Meanwhile, the post mortem report revealed the male giraffe 'Joy' died due to heart stroke. Symptoms of jaundice and anaemia were also found in the body of the animal, the report said.
Five-year old 'Joy' was brought here under the supervision of an eight-member expert team headed by Assistant Director of Nandankanan Dr Kamal Lochan Purohit.
