"We have not found involvement of any external forces so far, but CBI is conducting inquiries into some cases and if there is something, it will definitely come out," Union Home Joint Secretary Sambhu Singh, who is heading a seven-member central team to trouble-torn districts of Lower Assam, said here last night.
He, however, admitted that there were criminal and anti-social elements engaged in arms trade or trans-border trafficking across Nepal-India and Bangladesh, "but connecting them is not reasonable."
There was malicious campaign by misinformed people from social media sites in Pakistan and the process to find the actual sources of some photographs and messages uploaded to Facebook, Youtube and Twitter to fire communal passion, were being ascertained, Singh said.
He said so far 310 web sites have been blocked and many more were on the anvil as they came to notice.
"At the same time, some political statements might ignite passion of people leading to violence and one has to be very careful on that," he said.
The top priority in the riot-hit areas was to bring the situation under control as soon as possible and secondly to rehabilitate the displaced people, he said.
On relief measures, Singh said "there is no lacuna on the part of state or district administration and people are generally satisfied on whatever has been provided so far though in such a situation, there is bound to be some complaints from such a large number of inmates."
