A 22-year-old man is fighting for his life and three other people were also injured in a stabbing at a pub in east London.
Police were called to The Duke in Wood Street, Walthamstow, shortly after 8.15pm on Monday following reports of an attack involving a machete.
Three men were found with stab wounds inside the pub and a fourth was found injured in nearby Shernall Street.
Three of the men, aged 27, 31 and 42, are stable in hospital, while the 22-year-old remains in a life-threatening condition.
Police believe the attack was targeted. No arrests have been made.
“Whilst news of this kind is concerning, I would like to reassure the community that there is nothing to suggest any wider risk to the public.
“Officers will remain in the area throughout the day and I would encourage anyone with concerns to speak with them.”
Five roads near the pub remain closed and a police presence is expected to be in place throughout Tuesday.
A spokesman for the London Ambulance Service said: “We sent a number of resources to the scene, including four ambulance crews, members of our Tactical Response Unit, a member of our Motorcycle Response Unit and a first responder.
“We also dispatched London’s Air Ambulance.
“We treated four people at the scene. We took them all to a major trauma centre, two as a priority.”
