One man was stabbed to death and nine more injured between 6pm and 9:12 pm in London last night.
Two people were arrested by the police as they deployed emergency stop-and-search powers.
Two men were arrested after police were called to five separate reports of stabbings in Croydon between 6.56pm and 9.12pm on Friday.
Daily Mail reports that one of the two men reported to have been injured on Wisbeach Road was found dead at the scene, with two others left with life-threatening injuries following the night of violence.
There is no information to suggest the incidents are linked, the Metropolitan Police said.
The violence continued at 8.08pm, when police were again called to reports of two men with stab injuries.
One of the men was rushed to hospital before officers arrived, and another was found at the scene but later died.
At 8.51pm, two men were taken to hospital with stab injuries and one was last night in a life-threatening condition.
The final call was received at 9.12pm, where police arrested a man on suspicion of grievous bodily harm.
The victim, whose injuries are not believed to be life threatening, was also arrested.
Detective Superintendent Nicky Arrowsmith said: ‘Sadly, tonight we have seen a number of needless and completely abhorrent violent altercations, including one that has tragically resulted in a loss of life.
‘Officers will be on patrol throughout the night across the South Area Command Unit, with additional resources from the Violent Crime Taskforce and Territorial Support Group deployed to deter and prevent any further violence.’
Police asked anyone with information that could help officers investigating these incidents to make contact.
