Two men held over a shooting during rioting in Birmingham's Lozells area have been released without charge.
Bricks and bottles were thrown at police on Saturday
The men, aged 19 and 24, had been questioned over the death of a man in nearby Newtown early on Monday morning.
Racial tension was behind the rioting and followed an unsubstantiated claim that a 14-year-girl black girl had been attacked by a gang of Asian youths.
A heavy police presence overnight aimed to stop a repeat of the violence which saw one man stabbed on Saturday.
Isiah Young-Sam, 23, was stabbed to death on Carlyle Road by a group of up to 11 men.
Mr Young-Sam, an IT analyst at Birmingham City Council, died from a single stab wound to the chest. One of his friends was also stabbed in the back.
Police said he was an innocent victim and not involved in the rioting.
On Sunday night further disturbances took place in Lozells, where a heavy police presence was in place.
Hours later police were called to Melbourne Avenue in Newtown, in response to reports that a man had been seen with a firearm in the area.
There they found the body of a man who had been shot.
Birmingham Chamber of Commerce said on Tuesday it is concerned that the violence would have a knock-on effect on people thinking about setting up in business in the area.
Spokesman John Lamb said: "No one is going there shopping. It has become a ghost town."
But Bishop Joe Aldred from the Council of Black-Led Churches said people who had worked to restore calm in the area should be complimented.
"Things have calmed down but we must not move away from the underlying issues," he said.
The situation was more complicated than just issues between Asian and black populations, he said.
"It is deeper than that. Both communities mostly live on the outskirts of the city centre; a city centre which has had much money poured into it.
"The communities have issues of alienation and deprivation and that they are not part of the mainstream process."
