Followning the violence that erupted between protesters and police on Friday night in Chennai, hundreds of people on Saturday held a protest against Citizenship Amendment Act (CAA) and National Register of Citizens (NRC) at Washermanpet.
The fresh protests follow Friday's anti-CAA protest that turned violent when a group of protesters clashed with police in Chennai, leaving four police personnel injured.
The police later detained over 100 protesters, leading to more demonstrations near Mount Road Dargah at Anna Salai. It was, however, temporarily withdrawn.
Four police personnel -- a woman joint commissioner, two women constables and a sub-inspector -- were injured in stonepelting, the police said, even as reports emerged that some protesters were also hurt.
Joint Commissioner P Vijayakumari sustained injuries on her head, the police said, adding that those wounded were admitted to a hospital.
Earlier, some agitators were reportedly removed from the protest site forcibly, leading to a commotion between them and the police.
The protesters accused the police of resorting to a lathicharge.
Viswanathan held discussions with community elders and representatives of Muslim organisations, following which all those detained were released, the police said.
"An amicable decision was arrived at in the meeting with Muslim organisations and they have announced that the agitation will be withdrawn," a police officer said, adding that normalcy had returned to the area.
