Two teenage boys have been stabbed in separate incidents at London Tube stations.
Trains did not stop at Woodford station, in north-east London, while emergency services dealt with a stabbing at around 5.30pm on Monday.
The victim was taken to hospital and treated after being stabbed in the back.
DI Nia Mellor, of the British Transport Police, said: “This was a violent assault committed during rush hour on the Tube network, causing great concern to members of the travelling public.
“Fortunately, the victim’s injuries are not life-threatening and he is in a stable condition.
"Officers will be at the scene today carrying our further enquiries and I ask any witnesses to please get in touch.”
A BTP spokesman added: "The victim, a teenage boy, suffered an injury to his shoulder and was taken to hospital for treatment."
The official Central Line Twitter account confirmed the station's closure, posting: "At the moment trains are not stopping at the station. This is while police respond to an incident.
"We’ll let you all know when the station re-opens and trains are stopping normally."
The zone 4 station was later re-opened.
Earlier on Monday afternoon, shortly before 4pm, officers from the Met police were called to reports of a stabbing at Upney Underground station in east London after a fight broke out.
The station was closed while emergency services attended the victim.
Barking and Dagenham police said: "Police called to Upney Underground Station at 15.46hrs today - two teenage boys were found injured. Both taken to hospital & one is being treated for stab injuries.
"We await an update on their condition.
"There have been no arrests. A crime scene is in place. Enquiries continue."
BTP were not investigating the Upney incident because it was not inside the Tube station.
