GENEVA - Swiss authorities said they had arrested Guatemala's former chief of police on Friday in connection with a series of murders committed in the Central American country between 2004 and 2007.

Erwin Sperisen resigned in 2007 after eight murders raised fears that senior officials were linked to drug gangs.

Geneva prosecutor Olivier Jornot said that Sperisen, who was arrested five years after criminal complaints were first lodged in the Swiss city for killings in Guatemala, will be questioned over his alleged role in the killing of prisoners at the El Infiernito and Pavon prisons.

"He was head of the national police force during two campaigns to execute detainees and we will be looking into those murders," he told Reuters by telephone.
