Passenger shouts bomb threat after flight crew denies him a beer.

A Ryanair passenger was arrested Thursday night after he shouted a bomb threat while his plane was landing.

The man was aggravated that flight crew refused him a beer, and decided to exact revenge by claiming there was a bomb onboard, according to local reports.

The flight from Tenerife landed in Santiago de Compostela, Spain, at 9:28 p.m. local time.

As the plane was preparing to land, the man leapt out of his seat, ran down the aisle and shouted, "There’s a bomb! It’s going to explode!" according to local newspaper El Correo Gallego.

The pilot alerted ground crew at the airport of the incident. Police met the flight when it landed. They removed and detained the passenger and deactivated the local bomb alert after 20 minutes.

Once on the ground, some passengers reported hearing the man say, "I am going to set off a bomb because they didn't give me a beer."

"We will not tolerate unruly or disruptive behavior at any time and the safety and comfort of our customers, crew and aircraft is our number one priority," Ryanair said in a statement. "This is now a matter for local police."
