A train driver informed Southeastern that a passenger had been smoking drugs on board a train at 10.45pm last night (January 20).
A spokesperson for Southeastern says that the driver felt unwell as it was “right behind” the cab door.
The driver then took a break to have some air, and lines were suspended until the driver could continue.
Services between Grove Park and Bromley North were cancelled because of this.
Trains have since returned to normal.
British Transport Police has been approached for a comment.
A spokesperson for Southeastern said: “At 10.45pm the train driver advised that a passenger had been smoking drugs on the train.
“The driver felt unwell as it was right behind the cab door.
“The driver took a break to have some air.
“Line suspended until the driver felt fit to continue.”
