Three men were taken to hospital with injuries by a knife while attending a music festival.
Police were called at 7.35pm on Saturday to the Garage Nation festival in Hainault Forest Country Park with reports of a number of people “injured”.
Police, the London Ambulance Service and the London Air Ambulance attended the scene to discover three men with “stab and slash” injuries.
All three were taken to an east London Hospital with none life-threatening injuries and one man has since been discharged from hospital.
A fourth man was treated at the scene by medics but he left before police arrived.
Police are investigating one incident believed to involve all four men. No arrests have been made.
