Police and community leaders in Birmingham have appealed for calm after a man in his 20s was stabbed to death in disturbances in the Lozells area.
The disturbances have been linked to tensions in the past week
Three other people were stabbed, and a police officer was hit in the leg with a ball bearing fired from a gun.
The violence on Saturday is thought to have involved rival groups of youths.
Community leaders linked it to tensions in the past week over the alleged sexual assault of a 14-year-old-girl although no offence has been reported.
The confrontation between rioters and police began on Saturday evening and saw cars burned, property damaged, missiles thrown and groups of people wearing masks, or covering their faces with hoods.
Police said a number of arrests had been made. On Sunday, extra police were on the streets and a spokesman said it was "all quiet".
The disturbances broke out after a late afternoon public meeting at the New Testament Church of God over the alleged assault.
Two senior police officers, the Labour MP for Perry Barr, Khalid Mahmood, and church leaders had addressed the meeting.
Police say the violence was not a reaction to the meeting.
Mr Mahmood said there appeared to be a link between the violence and the alleged assault but the "vast majority" of people who attended the meeting were satisfied with explanations given by himself and police.
The MP said the majority of the community was close and no more than 30 youths were involved in the violence.
"I think the small number of people who were involved were predominantly from outside," he said.
"Today is going to be an important day. We need to make sure no other people come in from the outside to escalate this tension."
Bishop Joe Aldred from the Council of Black Led-Churches appealed for calm in the area.
"There's a clear condemnation from me and others in this community of the violence that's happened," he added.
The scene of the fatal stabbing remained cordoned off
He said "extremist elements" in the community seemed intent on using the incident "for their own criminal aims".
He told BBC Radio Five Live there were also underlying community tensions.
"At the root of it are primarily young people, but not just young people, from the African and Caribbean community.
"Their anger seemed to be directed in the first place at elements of the Asian community because they feel that it's Asian men who are the butt of the allegations here."
'A better place'
Assistant Chief Constable David Shaw denounced the violence.

"I can't really begin to describe how our sense of sorrow that we have lost someone from our community, that innocent people in the area have been attacked and injured, and that one of our colleagues who was out there trying to protect the public has been shot," he said.
"Over many years I've worked very hard to make this part of Birmingham a better and better place to live.
"We haven't been affected by some of the tensions that other parts of the country have seen and we are in no sense complacent when we say that."
Police said the investigation into the alleged sexual assault has been held back because no official complaint has been made.
A police spokeswoman said the dead person would not be named until next of kin had been informed.
A spokeswoman for West Midlands Ambulance Service said at least 12 people had been taken to the City Hospital.
