A flight heading for the UK from India had to turn back after a rat was seen on board, according to passengers.

Flight AI 131 was heading to Heathrow Airport from Mumbai on Wednesday (December 30) when the rodent was spotted.

Staff were reportedly alerted and while the plane was travelling over Iran, the plane turned back.

A replacement flight was arranged for passengers, while the plane was fumigated.

Air India said its engineers were examining reports of a rodent being behind the mid-air emergency manoeuvre.

However a spokesman said "the presence of the rodent was not confirmed", adding that the decision to turn back was for passenger safety.

Rats have the ability to cause haywire and mechanical problems on flights by chewing through wires.
