Police are appealing for witnesses who may have seen two people fleeing the scene of Tuesday’s murder in Peckham.
Officers are especially keen to speak to the driver of a car who was travelling down Rosemary Road at around 10.30pm and would have seen two people running in the opposite direction.
A murder investigation was launched after a 20-year-old local man was shot and stabbed at East Surrey Grove.
Police were called to reports of shots fired and on arrival at the scene, found the victim in a critical condition.
First Aid was administered before the London Ambulance Service arrived on the scene and took the man to a central London hospital.
He was pronounced dead shortly after arrival at 11.30pm after sustaining fatal gunshot and stab wounds.
Officers believe they know who the victim is and have informed the family, though no formal identification has yet taken place.
A post-mortem examination is due to take place at Greenwich Mortuary today.
