It's said that he who smelt it dealt it, but in this case everyone smelt it -- and it was so bad an airplane was forced to make an emergency landing.

A British Airways flight that was traveling to Dubai on Thursday night instead returned to England when a "smelly poo" in the toilet made continuing to the final destination untenable, according to the Mirror.

The cause of the unplanned landing was revealed by British politician Abhishek Sachdev, the Hertsmere councilor who represents Potters Bar Parkfield in England.

Sachdev tweeted:

Insane! Our BA flight to Dubai returned back to Heathrow because of a smelly poo in the toilet! 15hrs until next flight... #britishairways — Abhishek Sachdev (@CllrAbhiSach) March 12, 2015

The decision to turn back came just 30 minutes into the 7-hour flight, the Telegraph reports.

"We're very sorry for the discomfort to our customers," British Airways said in a statement to The Huffington Post. "​We provided them with hotel accommodation and rescheduled the flight to depart the next day."

The Airline declined to give further details on the incident and the "poo" culprit remains unknown.
