District Deputy Commissioner George Basumatary was transferred and Superintendent of Police Anup Kumar Singh suspended for allegedly failing to control the situation, official sources said.

The eight burnt bodies were found from Bodo villages of Sonaripara and Jhargaon villages, under Udalguri police station, which were attacked by illegal migrants with bows and arrows in the wee hours.

Besides setting ablaze houses in the two villages, several other dwellings in a neighbouring hamlet were also torched, the sources said.

The police shot dead two persons when they were trying to set fire to Bodo houses at Bhakatpara where a shoot-at-sight order is in vogue, they said adding about 50 persons were injured in the clashes so far.

Two bodies were found on Friday from a village under Rowta police station even as arson and looting in neighbouring Darrang district forced the administration to impose curfew in Dalgaon and Dhola on Friday and in Udalguri on Saturday.

Over 25 serious burn injury victims were shifted to the Gauhati Medical College Hospital while others were admitted to local hospitals.
