An air pistol and hunting knife were found in the hold of a Ryanair flight due to set off from Liverpool John Lennon Airport - after police were called to remove a disruptive passenger.
Officers found the weapons in Nerijus Stankaitis's luggage after he'd been taken off the flight bound for Lithuania.
The 26-year-old's luggage had been through all the pre-requisite security checks, but both the airport and Ryanair say there were no breaches of aviation security.
A spokesman for John Lennon Airport told the Liverpool Echo: "These items were located in hold luggage and not accessible to passengers.
"There has been no breach of aviation security however Merseyside Police are dealing with this incident."
A spokesman for the airline said: "As confirmed by Liverpool John Lennon Airport, this was not a breach of airport security."
However, as the Liverpool Echo points out, Department of Transport regulations state that firearms, including toy guns, knives and weapons or items that can be used as weapons, should not be taken on a plane, in hand or hold luggage.
Mr Stankaitis, of no fixed abode, was charged with possession of a prohibited weapon and possession of a bladed article at Liverpool Magistrates Court on Tuesday.
