Mohamed Abdi Hassan

Mohamed Abdi Hassan (, ), commonly known as Afweyne, is a convicted Somali pirate leader. He founded the Hobyo-Harardhere Piracy Network in 2005 and rapidly grew to become one of Somalia's preeminent pirates. In 2012 he began to leave the piracy "industry" and diversified his holdings into a multinational business empire. Hassan was arrested that year in Malaysia but was released as he had managed to obtain diplomatic immunity from Mogadishu. Hassan is from Harardhere, a port town in the south-central Galmudug region of Somalia. He hails from the Habar Gidir sub-clan of the Hawiye. Hassan has a son, Abdiqaadir, who works closely with him in his business operations.

In April 2012 Malaysian authorities captured Hassan. He was later released when a document from Somalia's then transitional government was received. A former president had reportedly given Hassan diplomatic status and a diplomatic passport as an incentive to quit the piracy business.

Later the same year, Belgium and Seychelles issued an INTERPOL Red Notice for Hassan's arrest.

Along with Tiiceey, Hassan was tried in Bruges, and sentenced in March 2016 to twenty years' imprisonment for leading the 2009 hijacking of the Pompei. He is the first pirate leader to be prosecuted by the international community.
