Honduran Ambassador, Jorge Gabrie, who accompanied Giammattei during the transfer, said the opposition politician surrendered voluntarily and that Honduras "expects him to have a fair trial, and that his life and human rights will be respected."

Giammattei was met by police at the front door of the Honduran embassy. He was taken to be arraigned at a Guatemala city court in an armored vehicle. The former presidential candidate is to face charges for extrajudicial executions during his tenure as Guatemala’s prisons chief.

A Guatemalan court also issued international arrest warrants for former Interior Minister Carlos Vielman, National Police Chief Erwin Sperisen, and Deputy Director of Investigations, Javier Figueroa, all currently living outside the country.
