The curfew, along with prohibitory orders under Section 144 CrPC, will remain in force till 7 am on Monday in order to maintain law and order in the district, Jalli said.
During the three-hour relaxation of the curfew, most shops and business establishments remained closed and only private vehicles were seen on the roads.
Internet services, too, remained suspended in Hailakandi, Karimganj and Cachar districts of Barak Valley since Friday night.
"The services will resume only after assessing the situation on Monday," said an official.
Following the clashes on Friday, curfew was imposed initially in Hailakandi town from 1 pm and later extended to the entire district from 6 pm, as the authorities apprehended breach of peace and tranquility.
One person had died in police firing and at least 15 people were injured, while more than 15 vehicles were damaged and 12 shops vandalised and set on fire in some parts of the town.
The district administration has begun assessing the damages to shops and properties.
Army and other paramilitary forces were also deployed in the district.
Hailakandi Superintendent of Police Mohneesh Mishra said the first and foremost priority of the administration is to restore normalcy, and then identify the miscreants behind the violence.
Jalli claimed that the incident is the "handiwork of some miscreants" and not a communal flare up as "there exists unity and amity among the communities" in the district.
Trouble started when a group of people decided to hold the Friday noon prayers on the road, located at Kali Bari point of the town, in protest against some motorcycles being damaged by people belonging to another community.
Police had to disperse the protesters initially by resorting to lathicharge followed by firing in the air.
