Passengers on a Jubilee line train at north Greenwich had to be led to safety after doors failed to open at North Greenwich station.
Passengers waited for 30 minutes and were eventually led through the drivers cab to exit.

The cause is not yet known. It follows a number of trains being taken out of service after cracked parts were discovered.
EDIT: The station has since closed for an apparently separate reason – a fire alert.
