"Maoist problem is the biggest security threat in the country. Thirty-five per cent of CRPF forces are deployed in different parts of Maoist-hit areas for containing their militancy," Sahay said.
He met Tripura Chief Minister Manik Sarkar and Governor Dr D Y Patil here.
He said, "Thirty-five per cent of CRPF forces are in Maoist infested areas. Thirty-three per cent of the forces are deployed in Jammu and Kashmir and 28 per cent are in North-East India and the rest are in other duties."
He said CRPF was being modernised to face any challenge.
"Now we have started using very sophisticated weapons and unmanned vehicles to detect mines as part of modernisation programmes so that we can face any eventuality," Sahay told reporters.
Sahay, who is also the former DG of Tripura Police said, "There has been a sea change in Tripura. It has emerged as the model state in the country in countering insurgency."
Tripura owned President's Colour last year. It is an honour given by President for successfully countering militancy in the country.
