A Tube driver has been arrested after allegedly being drunk in charge of a train, according to reports.
The 50-year-old man's colleagues reportedly smelled alcohol on the driver's breath after he had been at the controls of a northbound Jubilee Line train on Saturday afternoon.
The driver, who has not been named, allegedly kept driving the train after he had been meant to take a break.
He was arrested after failing to provide a breath sample.
A British Transport Police spokeswoman said: “I can confirm that officers were called to Queensbury London Underground station shortly after 3pm on Saturday.
“A 50-year-old man has been arrested under the Transport and Works Act and has been released on police bail until Wednesday, 2 April pending further enquiries.”
A TfL spokesman said the man had been suspended while investigations are continuing.
