A Monarch flight from Birmingham to Turkey had to be diverted to Bulgaria after a “disturbance” broke out on board.
The airline said the aircraft was forced to make an unscheduled landing at Sofia airport at about 5.40pm yesterday, where it was met by police.
Six people were removed before the aircraft continued its journey, a spokesman told the BBC.
The airline refused to confirm reports those arrested had been drunk.
The flight then landed at its scheduled destination of Dalaman in Turkey.
The incident comes just days after Jet2.com announced a ‘zero tolerance’ clampdown on disruptive passengers.
He hardline stance was introduced after a flight from Leeds Bradford airport to Alicante had to be diverted to Toulouse to offload a passenger who the airline said was “consuming illicit alcohol, using intimidating language and threatening behaviour.”
