Publicity Department member of the ULFA(I) Romel Asom in a statement e-mailed to PTI here said, “The ULFA (I) would like to make it clear to all concerned authorities that our organisation does not have any involvement in the firing incident last night.”

A bandh, called by the All Assam Bengali Federation, is also being observed on Friday in the district protesting against the attack.

As the day passed by, the protests grew and women in Tinsukia blocked the Dhola-Tinsukia highway. They resorted to burning of tyres to express their outcry against the murder of five people, including three of a family.

In view of Thursday night’s attack, security has been beefed up in the state with the chief minister directing all deputy commissioners and superintendents of police to remain alert.

Condemning “the killing of innocent people”, Sonowal had said, “Strong action will be taken against the perpetrators of this dastardly violence. We will not tolerate such cowardly act.”
