Commuters could face delays if they are travelling to parts of Redbridge tonight.
Transport for London (TfL) confirmed that trains are not currently stopping at Woodford Station due to an "incident".
A TfL spokesman tweeted: "Woodford: 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."
