Manchester Airport was partially evacuated after a “suspicious package” was found during a security search.
Passengers were held on planes while police placed the area on lockdown to investigate the item in terminal two.
The item, a laptop, was deemed suspicious as the device had more wiring than expected, the Manchester Evening News reported.
A controlled explosion was carried out, police said.
The airport’s operations have since returned to normal after the package was found not to be suspicious.
A spokesman for Greater Manchester Police said: “Shortly before 5.45pm on Wednesday 25 April 2018, police were called to reports of a suspicious item at Terminal 2 of Manchester Airport.
“Officers attended and on examination of the item requested the assistance of the bomb disposal unit.
“A controlled explosion has been carried out as a precaution, and the cordon has been lifted.
“There are not believed to be any suspicious circumstances. Enquiries are ongoing.”
