A District Line station has been shut for over 12 hours as police investigate a stabbing.
The British Transport Police (BTP) were called to Becontree underground station at around 10pm on Wednesday following reports of a serious assault.
Paramedics also attended the scene and a person was taken to hospital with stab injuries.
The BTP believe that their wounds are not considered to be life-threatening or life-changing.
Police enquiries into the incident are ongoing but the attack is believed to be an isolated incident.
Detective Inspector Marvin Bruno said: "There is no place for violence on the railway network, and our detectives and officers are working tirelessly to investigate this incident.
“While we believe this was an isolated incident, the public will see an increase in high-visibility patrols in the area and across the network to provide reassurance."
