A murder investigation has been launched after a man was fatally stabbed at a youth club in Brixton.
DCI Mick Norman from the Homicide and Major Crime Command said: “This was an appalling attack on a young man in a youth centre - a place where he was entitled to feel safe.
“All the early indications are that this attack was premeditated and targeted.
“My team need to hear from those who were at the youth centre either before, during or after that attack. The youth centre was open at the time and sadly many young people present would have witnessed what unfolded
“Many of them will be shocked and traumatised by what they saw and perhaps fearful of potential reprisals if they speak to police. I would urge them to get in touch and if they want to do so anonymously they can either call Crimestoppers via 0800 555 111 or give information anonymously online via the Fearless website.
“Anyone with information about the attacker(s) is also urged to get in touch.”
Police were called at approximately 18:45hrs on Thursday, 21 February to reports of a man stabbed on Minet Road, SW9.
Officers attended and provided the victim with first aid. London Ambulance Service and London's Air Ambulance also attended.
The man, aged 23, was pronounced dead at the scene at 19:27hrs.
His next of kin have now been informed.
Although we await formal identification officers are confident they know the identity of the deceased.
A post-mortem examination will be held in due course.
The Homicide and Major Crime Command have been informed and will be leading the investigation.
A number of detailed forensic and CCTV footage related enquiries are in hand and police are appealing for information.
At this early stage, no arrests have been made. Enquiries into the full circumstances of the attack are ongoing.
A crime scene remains in place.
Detective Superintendent Sian Thomas from Central South which includes Lambeth said:
“Tragically the local community is now coming to terms with the senseless loss of life. To take a young life at a place designed to help support and nurture young people is appalling.
“I completely understand the alarm and concern it has raised from those who live and work in the area and particularly for young people, many of who used the youth enterprise centre regularly.
"A crime scene will remain in place today as officers continue their painstaking work to piece together the details of the attack.
"I would urge the local community to be patient and cooperate where possible with the work detectives are getting on with in the area.
"My officers will be out working to support investigators today and be there to talk to the public and listen to the concerns they have. Neighbourhood patrols will be stepped up in the area and locals can expect to see more police. I would urge anyone with information on the attack to contact police without delay."
Anyone with information is asked to call police via 101 quoting reference 6141/21Feb.
