Two people were killed after police fired Wednesday at protesters in Assam near the border with Nagaland, leading to curfew in Golaghat district, officials said.
Hundreds of men and women took to the streets in Rongajan and Arengapathar areas in the district to denounce "police atrocities" Tuesday which left one person dead and 20 injured.
The trouble erupted over a border conflict between the two states.
On Wednesday, police first used batons to disperse the crowd but failed to restore order.
The crowds, armed with sickles and other weapons, became unruly in the afternoon and attacked many vehicles on the roads in Rongajan. They also targeted public property, a police official said.

Of the 14 injured, nine were taken to the Jorhat Medical College Hospital, said Assam Home Commissioner G.D. Tripathy.
Chief Minister Tarun Gogoi Wednesday blamed the central government for the imbroglio along the Assam-Nagaland border and said the Narendra Modi government had not taken the issue seriously.
"It was unfortunate that one person died. We have ordered an inquiry and a senior police official has been suspended," Gogoi said.
"The neutral force (CRPF) deployed in the border is responsible for law and order," he went on.
"I take my responsibility as chief minister but the centre, particularly the home minister, is also responsible. They have not been taking the matter as seriously as they should have," Gogoi said.
Gogoi said he had taken up the matter with his Nagaland counterpart T.R. Zeliang. He asked police to use non-lethal weapons like rubber bullets and water cannons while dealing with mass protests.
