Police are appealing for witnesses and information following the stabbing of two teenage boys in Streatham.
Police were called at 17:30hrs on Wednesday, 30 December 2015, to reports of a 16-year-old boy and a 17-year old boy who had been stabbed in Mountearl Gardens, SW16.
Officers and the London Ambulance Service (LAS) attended the scene and the victims were taken to a south London hospital with stab wounds to their torsos.
The 17-year-old boy was treated for his injuries and has since been discharged from hospital. The 16-year-old boy currently remains in hospital in a critical condition.
Detectives from Lambeth CID are investigating.
At this early stage detectives believe that the victims sustained their injuries after two mopeds each with a rider and pillion passenger approached them. The pillion passengers then attacked the victims before fleeing on the waiting mopeds, heading in the direction of Mount Nod Road.
Neither of the pillion passengers is believed to have worn a helmet.
No arrests have been made and enquires continue.
Detective Chief Inspector Jim Redmond from Lambeth CID said: "This was a vicious and violent attack which has left a teenage boy in a critical condition. The incident happened late in the afternoon and there would have been a number of people in and around the area who may have witnessed the events in the lead up to the attack, the stabbings themselves or the moped riders with their pillion passengers fleeing the scene.
“It is of paramount importance that we find those responsible and I would urge anyone with any information no matter how small to get in contact with us."
Anyone who witnessed the incident or has any information is asked to contact DS Ion at Lambeth CID on 101 or Crimestoppers anonymously on 0800 555 111.
