The Jharkhand forest department has put over 50 trap cameras, one drone and a large number of officials but the 'man-eater' leopard, which killed four children since December 10 in Palamu division, is still traceless, an official said on Sunday.

Now, the department has roped in Hyderabad-based celebrated hunter Nawab Shafath Ali Khan to control the big cat. It is suspected that all four including three in Garhwa and one in Latehar district were killed by the same leopard. The victims are in the age group of six and 12 years.
