A teenager was stabbed and there was a mass brawl at the funfair in East Barnet last night.

Police were called at 8.34pm on Friday to Oak Hill Park, off Parkside Gardens, following reports that a group of males were fighting and someone had been stabbed.

Officers arrived alongside paramedics from the London Ambulance Service but the youths ran off when police arrived.

Police searched the area and found an 18-year-old man in Churchill Road with a stab injury.

He was taken to hospital, where his condition has been assessed as not life-threatening or life-changing.

No arrests have been made and enquiries are ongoing.

Footage has surfaced online showing someone dressed in black with white trainers sprinting through the park holding what appears to be a knife.  

Dozens of people are in the footage, shot on the hill near the park's playground, with the recorder heard telling people "run away, run away".

Another shot shows people gathered around what appears to be someone being treated by Churchill Road.

There is also a video taken by the funfair's arcade showing a large group pushing and shoving around people fighting on the floor.
