An intruder, high on drugs, broke into German Chancellor Angela Merkel's official aircraft on July 25 and partied on it for hours, in his underwear, before being apprehended. The incident happened last month, but has come into focus after a police report was leaked to German media.

The incident took place on one of the official Airbus 319 used by the German Chancellor while it was unoccupied in a closed high security military section of Cologne airport.

The man, whom the German national daily newspaper Die Welt termed as 'a 24-year old, German Turk' climbed onto Merkel's highly secured aircraft breaching security protocol. The incident will raise serious questions on security of the German Chancellor and implicate police and Air Force security personnel for their failure.

This name of intruder was said to be Volkan T. German media called him "Volkan the intruder." Die Welt reported that Volkan is a bodybuilder of Turkish descent.

Strangely enough the man got access to the plane relatively easily. He told the guard he was there for a wedding party. He then climbed over the barbed wire and got into the aircraft with a bag full of marijuana and ecstasy pills.

Raucous, One-man Party

Once onboard the aircraft, he began to have fun. Der Spiegel, German weekly news magazine described Volkan's party as "a raucous, one-man party."

The magazine reported that he stripped down to his underpants, sprayed fire extinguisher foam around the elegant cream and beige interior, pushed buttons in the cockpit, released an inflatable emergency slide and danced on the wing of the Airbus 319.

Damaged Caused

Volkan is believed to have caused €100,000 ($133,720) worth of damage, but it could have been worse still - the door to the cockpit was open, and he actually tried to start the engine. The Airbus was loaded with up to eight tons of fuel and technically, the intruder could have taken off or at least gotten it rolling.

Police and security personnel took almost four hours to get the intruder off the plane.

The plane, which is also used by other top state officials including President Joachim Gauck, was delivered three years ago and is one of two medium range A319 jets in the government fleet. It has a private office, a conference room that seats 12 and a main cabin with room for 32.
