Detectives investigating the murder of a 21-year-old man in Croydon have reiterated their appeals for witnesses.
On Monday, 31 October, police were called just after 20:10hrs by the London Ambulance Service (LAS) to Gloucester Road in Croydon following reports of a stabbing.
Officers attended and found three men, aged in their 20s, suffering from stab injuries.
One of the men - aged 22 [victim 1] - was treated at the scene but was later pronounced dead at the scene.
Next of kin have been informed. Formal identification has now taken place and police can confirm the deceased is Scott Kouebitra, 22, (22.11.93) from Sutton.
A post-mortem examination was held on Wednesday, 2 November, at Croydon Mortuary and gave the cause of death as multiple stab wounds.
The other two men - aged 27 [victim 2] and 21 [victim 3] - taken to a south London hospital with stab wounds continue to receive treatment; their injuries are not believed to be life-threatening.
Following the incident, officers were informed that a fourth man - aged 22 [victim 4] - had attended a south London hospital with stab injuries. His injuries are also not thought to be life-threatening. He also continues to receive treatment.
A fifth man - aged 20 [victim 5] - was also injured, but not stabbed, in the attack. This person was also known to the victim's group. Officers cannot rule out that there may be other injured persons not yet spoken to by police and would like them to come forward.
Detectives from the Homicide and Major Crime Command are investigating.
Officers investigating the case said that the suspect group consisted of approximately seven males all wearing masks, scarves, balaclavas and or hoods.
They arrived in Gloucester Road in two vehicles from the direction of St James' Road. The vehicles are described as one light vehicle and one dark vehicle. They exited the two vehicles and entered the park carrying weapons.
The altercation then spilled out onto Gloucester Road. Suspects were on the scene for no longer than a minute and half. The vehicles then left in the direction of St James' Road.
At this stage it is unclear what those weapons were but detectives know at least some of them were knives because the victims were stabbed.
An incident room has opened at Sutton under Detective Chief Inspector Sam Price.
DCI Price said: "We now know that there were a large number of people in and around St George's Field Park on the evening of the fatal attack and the other stabbings.
"If you were there and saw anything that could assist investigators I would urge you to get in touch.
"The park is used regularly by dog walkers and they may have been in the park that evening and some people who came to the aid of the victims have not spoken to the police."
She added: "There has been a lot of speculation concerning the motive for this attack and whether this was a Halloween related antisocial behaviour incident that got out of control. Whilst we are retaining an open mind, we believe that all the victims are known to each other and as a result early indications suggest that this was not a random attack. Many of the group we are seeking to trace did wear balaclavas and masks as they fled the scene.
"I would also appeal to friends and family of the suspects to come forward if they have any information into what happened.
"A young man has had his life taken away - your information could be vital to piecing together the events that unfolded that evening."
