"I do not claim that Maoist activities have been cleaned up in the state. The situation has improved to a great extent as we have been able to contain them," Rath told newsmen here.
Rath urged the policemen to remain alert as the rebel outfits reply more on guerrilla tactics and can attack anywhere anytime.
Maoists had torched about a dozen vehicles engaged in road construction work as the contractor did not pay the ransom demanded by them, he said.
The other incident took place in Porhat region where there was no deployment of security forces, Rath said.
He said the proposal for setting up of a composite check post in bordering areas with neighbouring states have been approved by the state government and would be implemented soon.
