Raipur, Nov 21 (IANS): Claiming that poachers have virtually taken over Chhattisgarh's sanctuaries, Congress leader Ajit Jogi Monday sought a CBI probe into a spate of killings of tigers and other wild animals in the state.

"Poachers have done massive networking in the state, they have virtually taken command over sanctuaries and parks. Dozens of tigers, leopards, elephants and other animals were killed in the state in recent months and the poachers supplied organs of these animals to China and the US," Jogi said in a statement.

"The CBI should probe the spate of killings of rare wild animals in Chhattisgarh," he added.

Last week, a six-year-old tigress was killed in Bhoramdev sanctuary in Kawardha, the home district of Chief Minister Raman Singh. In September, a mob lynched a tigress in presence of forest officials in Rajnandgaon district.

Meanwhile, the forest department Monday said four people, included two forest department staff, have been arrested for the Bhoramdev sanctuary killing.
