"Whatever protection CRPF should have given, they could not give. That is why the violence took place and people died," Gogoi told reporters here.
When asked specifically does it mean that CRPF failed to discharge its duties, he said, "I will not exactly say that."
Gogoi said he will write to the Centre about this and alleged inaction by the CRPF Commandant, who people say to be a Zemi Naga.
The police of both the states cannot be present there but normal day-to-day security is given by a "neutral force".
"Earlier Assam Rifles was there and then CRPF was posted. That land is disputed and is under neither Assam's nor Nagaland's control. It is a Centre-controlled area," Gogoi said.
In 1988, the Assam government had filed a case in the Supreme Court, which formed a Mediation Committee to give a report on the disputed land.
Talking about the present spate of violence, Gogoi said he suspects "involvement of NSCN militants but no proof has been found yet".
