In an incident which took place over two years ago, the unnamed Saudi citizen smuggled 115 grams of cannabis and nearly 2,000 stimulant pills on to the roof of the main prison in Jeddah, according to the Saudi Gazette.
A 45cm-by-45cm drone with four propellers was used to transport the drugs to barracks seven and eight of Briman prison. A report submitted to the court said the drone took off from a supermarket roof close to the prison and was operated by the brother of the convict.
