The Met have issued two separate appeals for witnesses relating to two incidents that took place in Southwark last week.
The first incident took place in Elephant and Castle on October 3 at around 6.20pm when a 16 year old boy was attacked and stabbed in the arm.
The fight took place on the street near the Elephant and Castle Shopping Centre on New Kent Road before the suspects, described as black males, made off down New Kent Road.
The 16 year old boy was taken to hospital before being discharged but will require ongoing treatment.
Detective constable Caroline Jeffery said: “This fight took place during rush hour so there would have been many motorists and pedestrians in and around the Elephant and Castle roundabout at the time.
“I would ask anyone who witnessed this fight or any motorists who may have recorded some of the incident on dashcam footage to get in contact with police.
“A male was seriously assaulted and we need to find the people responsible.”

The second incident took place on Sunday, October 6, at around 2.25pm in Kinsale Road, near to the junction of Dewar Street, Peckham, where a man was reportedly kidnapped after he was forced into the back of car.
A witness reported seeing a man being forced into a black BMW car by three other males. The car then drove off in the direction of Dewar Street before turning into Fenwick Road and Amott Road.
Police recovered the vehicle, registration YE19 NDX, and four men have been arrested on suspicion of kidnap. All four remain in custody at this time.
