NEW DELHI, India (CNN) -- The death toll has risen to 47 in clashes between tribal people and Muslims in India's remote northeastern state of Assam, authorities said Tuesday.
State Home Commissioner Rajiv Kumar Bora told CNN that about 100,000 people have sought refuge in around 50 relief camps since deadly rioting broke out Friday between the Bodo tribesmen and what locals suspect are Bangladeshi settlers.
"No fresh incident has happened over the past 24 hours," Bora said. "But some people injured in the clashes have died in hospitals, and some more dead bodies have been recovered."
Police have made some preventive arrests and are investigating the cause of the fighting in the Udalguri and Darrang districts, he added.
"The situation is under control, but we can't call it normal until those displaced feel safe enough to return to their homes," Bora said.
Authorities are looking into whether decades-old rivalry between the Bodo and Muslims caused them to attack each other with bows, arrows and spears.
At least 22 deaths resulted from police firing, said Assam's Police Inspector General B. J. Mahanta.
