'Along with the blood stains, we had also sent a part of a tooth for forensic examination,' Kumar said.

Kumar ruled out rumours of any political interference in the tiger poaching probe, which has seen the arrest of five persons for allegedly killing the tiger in February this year.

Incidentally, two senior forest range officials in the forefront of the tiger poaching case have been booked by the state police for allegedly beating two persons accused of killing the animal and trying to destroy evidence.

The role of the forest department top brass has been under the cloud ever since the tiger poaching incident came to the fore some months back.

Senior forest department officials, including the CCF, had dismissed reports of a poached tiger in the Mhadei wildlife sanctuary in North Goa, until a local newspaper published photographs of the snared and poached tiger, which was allegedly taken by the poachers.
