A Swiss court has sentenced Guatemala's former police chief to life in prison after convicting him of involvement in seven extrajudicial killings.

Erwin Sperisen was arrested in Switzerland in 2012 and accused of planning and directing operations to kill detainees during his tenure as police chief from 2004-2007. He was tried in Switzerland because he has dual Swiss and Guatemalan nationality.

Geneva's criminal court said it found Sperisen guilty Friday of being jointly responsible for six killings and directly responsible for a seventh.

Sperisen, who denied the charges, was acquitted of three further killings after a three-week trial.
