An official said that the situation in the city had come back to normal and there was no report of any untoward incident in the past two days.
Police officials said that eight cases had been registered in which hundreds of people had been booked for offences like damaging public property, rioting and arson.
"Action against those who indulged in violence has begun and we are identifying them through eye-witness accounts, CCTV footage and video recordings," he said.
Section 144 of the Criminal Procedure Code had been revoked in the city but CrPC section 37/13 continued, the official said.
Several shops and scores of vehicles were torched during the riots.
