Social media users were quick to react earlier after Southeastern tweeted the bizarre reason why a train was running late.

The company said the train from Bromley South to Victoria was late departing because of β€œthe driver becoming locked in the on board toilet”.

They then apologised for the delay and used a GIF showing Lisa Simpson demanding someone open the door.

Tweets then quickly flooded in after the witty announcement although presumably those on board were not too impressed.

Some mocked Southeastern by labelling it as "fake news" because β€œthere is no way the toilet would have been working in the first place”.

Here are the best of the reactions:
