The office of President Juan Orlando Hernández said the head of state “has today (Friday) accepted the resignation of the secretary for foreign affairs and international cooperation, Arturo Corrales.”

Corrales was Orlando’s security minister during an alleged cover-up of the police involvement, which came to light through recent reporting by the Honduran newspaper El Heraldo.

The daily cited a security ministry document revealing that senior police officers ordered the assassination of Honduras’ top anti-drug official, Arístides González, in December 2009.

It also said the group of police ordered hits on a state prosecutor, Orlando Chávez, in April 2013, and on a former security ministry consultant, Alfredo Landaverde, in December 2014.

The hierarchy of the security ministry in place between 2009 and 2014 covered up the information, the newspaper said.

Corrales was security minister for one year, from January 2014 until January 2015, when he was made foreign minister.

Honduras’ public ministry, which handles state prosecutions, opened an investigation last week after a raid on the police headquarters turned up evidence regarding González’s murder.

The president has asked Congress to approve an emergency decree aimed at accelerating a clean-up of the 12,000-strong police force that has been dragging on for four years now.

That process started in early 2011 when it was discovered that it was riddled with officers working for narcotics cartels, hitmen and other criminals.

Authorities believe more than one in 10 of the officers is dirty and must be booted from the police force.
