Sri Lankan authorities said Wednesday they had the situation "under control" after mosques and Muslim-owned shops and businesses were targeted in a violent backlash after the Easter Sunday terror attacks.
A second overnight curfew imposed nationwide ensured there was no repeat of Monday's violence against Muslims, who make up some 10 per cent of Sri Lanka's population of 21 million.
Many Muslims have been bracing for revenge attacks since three churches and three luxury hotels were bombed by local Islamist extremists on April 21, killing 258 people.
"The situation is now totally under control," said military spokesman Sumith Atapattu.
"There were no incidents of violence overnight and we are arresting groups of people responsible for taking part in mob attacks."
Ruwan Gunasekera, a police spokesman, said that more than 80 people were in custody as of Tuesday evening.
Official sources said police deployed special teams to review CCTV camera footage to identify the perpetrators of the riots and many arrests were being made on this basis.
More police and army units were seen deployed in the troubled area as the authorities lifted the nationwide curfew on Wednesday morning.
But Muslims in North-West Province remained nervous and stayed indoors Wednesday, after sword-wielding rioters killed one man late Monday while vandalising scores of shops and mosques.
In Bingiriya, where some 2,000 people went on the rampage, Muslim cleric M.I.M. Siddeeque said the community was worried.
"The situation is now totally under control. There were no incidents of violence overnight and we are arresting groups of people responsible for taking part in mob attacks.
"Our people are still afraid to go out," he told AFP by telephone.
Military spokesman Atapattu said security forces were arresting small groups of suspected trouble-makers and handing them over to police.
They were being held under emergency laws under which convicts can be jailed up to 10 years, police spokesman Gunasekera said.
Among those detained was Amith Weerasinghe, a man from Sri Lanka's majority Buddhist Sinhalese community and on bail for his role in similar riots in March last year in the central Kandy district.
Another man arrested was identified as Namal Kumara, a deserter from both the army and the air force for his alleged role in leading mobs.

Meanwhile, the police also made several changes in the command structure by removing senior officers in the troubled areas after allegations that officials did nothing to stop the rioters.
Parliamentary speaker Karu Jayasuriya condemned the violence and appealed for calm.
"The attacks on mosques, the burning of houses and shops, the attacks on innocent people cannot be condoned in any way," Jayasuriya said in a statement.

The attacks came during the Muslim holy fasting month of Ramadan.

Internet service providers said the telecoms regulator on Tuesday extended a social media ban to Twitter.
Earlier, Facebook, WhatsApp, YouTube and Instagram had been blocked to prevent the spread of messages inciting violence.

Intelligence warnings from abroad alerting to possible attacks by Islamist extremists were ignored ahead of the multiple bombings of churches and upscale hotels on April 21 that killed 253 people and injured nearly 500.
The April 21 attacks, claimed by Daesh, targeted churches and hotels, mostly in Colombo, killing more than 250 people and fuelling fears of a backlash against the island nation’s minority Muslims.

It said there would be no limits on the number of visitors allowed to visit people in their own homes but they must ensure that there is enough space for everyone to keep their distance from each other and make sure there is enough fresh air.
Restrictions will be lifted in three phases, culminating in the curfew completely ending — with the exception of the holy city of Makkah — from June 21, the state news agency reported in a statement early on Tuesday.
