A number of buildings have been evacuated after 200 square metres of scaffolding collapsed on to a north London street in heavy winds.
London Fire Brigade said the measure was taken as a precaution as two fire engines and three rescue units attended the scene in Pond Street, Hampstead Heath.
Video posted to social media showed the scaffolding strewn across the road as emergency services urged people to step back from the cordon.
London Fire Brigade said no-one was injured in the incident.
A London Ambulance Service spokesperson said: “We were called at 2:45pm today (7 March) to reports of an incident on Pond Street, Hampstead.
“We sent an ambulance crew, an incident response officer, a single responder in a car and an advanced paramedic to the scene. We also dispatched London’s Air Ambulance and members of our Hazardous Area Response Team.
“We are working closely with other members of the emergency services and remain at the scene.”
