New Delhi, March 29 : Delhi Police's recent seizure of two 'Bengal tiger skins' from five smugglers has raised questions about the authenticity of the recovered skins. The investigation has revealed that one of the skins was not of a tiger, and examination of the other is still ongoing. According to sources at the Central wildlife agency, preliminary examination indicated that the black stripes on the first skin were likely painted, suggesting that it was not a real tiger skin. Sources suggest it may be a dog skin. The Wildlife Institute of India (WII) in Dehradun is currently conducting a full examination of both skins, with the final report still pending. Police had announced last week that they had busted a smuggling ring dealing in Bengal tiger skins and arrested five individuals.

At the instance of accused Mohit and Shivam, one more tiger's skin was recovered from a jungle area near Qutub Vihar, Delhi. and Rahul was also arrested," Yadav said. "Shivam was the main source for tiger's skins. He had four in his possession. He had approached Mohit and asked him to look for some buyers, and gave him one skin as a sample.
