The Office of the Attorney General in Switzerland has confirmed it is investigating The former Gambian Interior Minister Ousman Sonko for possible crimes against humanity, the BBC is reporting.
Mr Sonko, who is seeking asylum in Switzerland, was taken into custody last month after a Geneva-based campaign group, Trial International, filed a criminal complaint accusing him of serious assault, coercion and false imprisonment, relating to his time in office in The Gambia.
The Attorney General’s office said it “would not rule out a suspicion of crimes against humanity”.
Mr Sonko has not commented on the accusations against him.
The former interior minister was one of the longest-serving members of ex-President Yahya Jammeh’s regime. He was also head of police but fell out with his boss in November last year – a month before the presidential election, which Mr Jammeh lost.
