Extra police patrols will be put in place in the Old Kent Road area as police continue to appeal for witnesses to an altercation on Wednesday afternoon that left three youths suffering stab wounds.
Southwark detectives have renewed their appeal for members of the public who were in the Old Kent Road at about 4.30pm on Wednesday 28 November to contact them with any information they may have about the incident.
Officers were called at approximately 4.40pm to reports of three youths suffering stab wounds.
The three males, all aged 16, were taken to separate London hospitals.
One victim is in a stable condition with a head injury, one is in a stable condition with a punctured lung and the other who suffered minor injuries has now been discharged.
It is believed the three youths were involved in an altercation with a group of black males and enquiries continue into the motive behind the attack. A weapon has been recovered.
