"The Centre is seized of the matter and is in constant touch with me," Gogoi told PTI.
He said Prime Minister Manmohan Singh, Union Home Minister P Chidambaram and UPA chairperson Sonia Gandhi had spoken to him over telephone to take stock of the situation.
The army, police and paramilitary forces were deployed and more forces were being sent to deal with the situation, he said.
Noting that the situation was "volatile and tense", he said over 40,000 people have fled their homes.
"People in remote areas have abandoned their house out of panic and the figure may be even more by now, but strict instruction have been issued to provide them security," he said.
"The situation is fast changing and it is difficult to provide a comprehensive picture. I have deputed four ministers to take stock of the situation and report back to me," Gogoi said.
Describing the situation as 'unfortunate", he said, "It was hard to forsee such a situation in a case when mob is involved. Our forces are taking all steps to maintain peace."
