Trains have been delayed after “disruptive passengers” caused problems.

The 11.48am Lowestoft to Norwich service had to be delayed at Cantley station and was around 25 minutes late after a smoke alarm was set off in the toilets of the train.

A Greater Anglia spokesman said that this was “due to disruptive passengers.”

All lines are now open, but a statement on the Greater Anglia website said: “Due to an earlier disruptive passenger incident, services have been delayed.

“The 11.48 Lowestoft to Norwich service has developed a fault, from the smoke alarm sounding in the toilet, and has been delayed at Cantley Station.

“The driver has reset the on board systems and is now on the move.”
