Doherty was arrested after he allegedly injected drugs on a flight from London to Geneva.
The singer had locked himself in the bathroom for 30 minutes. Cabin crew began to worry and when he came out of the bathroom he reportedly looked dazed and "obviously intoxicated".
One passenger told Britain’s Daily Star newspaper: "The crew knocked on the door but Pete didn't come out. They eventually managed to get in 10 minutes before the plane landed. Pete was taken back to his seat and he looked completely out of it. One of the crew took the needle out of the toilet wrapped in a tissue."
Pete was arrested once the plane arrived in Switzerland. It is unclear as to why he was charged with but he was ordered to pay a fine and was released.
This just proves old habits die hard!
