A leading Somali pirate has been sentenced to 20 years in prison by a Belgian court.

Belgian authorities managed to trick Mohamed Abdi Hassan in 2014, when they brought him to Europe for a documentary on piracy.

Hassan, who is also known as Afwanye or Mohamed Garfanje, was suspected of leading the pirates who took hostage the crew of the Belgian ship Pompei in 2009.

He is considered to be a major figure in piracy.

The Belgian court has also found the 58-year-old guilty of torture, according to the Belga news agency.

Hassan is expected to appeal the ruling.

Another suspect who was arrested with Hassan was sentenced to five years, but not for his involvement in the Pompei hijacking.
