Prosecutors believe the 53-year-old suspect Gibril Massaquoi – who denies any wrongdoing – murdered, raped and mutilated civilians while he was in a high position in Revolutionary United Front.
Last year, Massaquoi, who has lived in Finland for many years, was acquitted of all charges by a lower Finnish court. It said a significant doubt remained over his participation in the suspected acts due to witnesses changing their testimonies. Liberia endured conflicts that killed around 250,000 people between 1989 and 2003, when Taylor, who seized power in a coup that sparked the rebellion, stepped down.
Taylor was convicted to 50 years in prison for war crimes by a U.N.-backed Special Court for Sierra Leone in The Hague in 2013.
