A critical incident has been declared in north-east London, an MP for the area said, amid reports of several people being stabbed at a Tube station.
There are station and road closures in place. The police, ambulance service, and fire brigade are responding. One male detained.
Police are at an incident in the Hainault area. Please follow the instructions of police officers on the ground. A man has been arrested.
I would urge people not to speculate until details are confirmed or post footage on social media.
