A holiday jet was evacuated shortly after it touched down due to an electrical fault which caused a smell of burning in the cabin.
East Midlands Airport said three other flights were diverted to Birmingham after the precautionary evacuation of an aircraft operated by low fare airline Jet2.
A spokeswoman for Jet2 confirmed its service from Ibiza to East Midlands was evacuated due to a "minor" electrical problem.
The spokeswoman said: "Following a safe arrival last night at East Midlands Airport, flight LS644 from Ibiza had to be evacuated once on stand as a precautionary safety measure.
"All passengers were looked after by our airport team. A full investigation is now under way."
In a statement giving further details of the incident, Jet2 said the Boeing 737 was carrying 147 passengers and crew.
The airline added: "We decided to disembark passengers as quickly as possible as a precautionary safety measure because a minor electrical problem led to some smoke in the cabin."
