West Midlands police have declared a major incident in Birmingham city centre after a series of stabbings.
Police said there were a number of victims, but the severity of their injuries was not immediately known. They urged people to stay away from the area, which was cordoned off, and warned of a greater police presence.
Officers were initially called to reports of a stabbing at about 12.30am on Sunday, with “a number of other stabbings” reported in the area shortly after.
Police later said they were aware of “comments that gunshots were fired” but that no reports of gunfire had been made to them.
One witness, Cara, told BBC Radio 5 live she thought it was “one group of boys against another group of boys” and that she had heard racial slurs during the incident.
She said: “They were not just having an argument and then fighting, it was straight into fists being thrown. There was not much talking going on.”
In a statement, West Midland police said: “We are aware of a number of injured people, but at the moment we are not in a position to say how many or how serious.
“However, all emergency services are working together at the scene, and making sure that those who are injured receive medical care.
“Work is still going on to establish what has happened, and could take some time before we are in a position to confirm anything. At this early stage it would not be appropriate to speculate on the causes of the incident.”
