Guillermo Arturo Zuany Portillo resigned as head of strategic operations for the Chihuahua prosecutor’s office after foreign agents were revealed to have joined a drug raid. The April operation in Morelos municipality sparked investigations into a possible violation of national sovereignty.
Guillermo Arturo Zuany Portillo submitted his resignation on Tuesday afternoon after prosecutor Wendy Chávez reported videos showing a foreign agent carrying a firearm inside the Fiscalía de Operaciones Estratégicas facilities. Administrative staff immediately began processing his dismissal.
The operation took place between April 16 and 19 in the community of El Pinal to seize a synthetic drug laboratory. Four foreign individuals joined the convoy wearing civilian clothes and without official insignia. On April 19 a traffic accident killed two agents from the Agencia Estatal de Investigación and two Americans.
Governor Maru Campos defended the operation and stated it was carried out by Mexican agencies with legal authority. She said she neither authorized nor knew about the foreign presence and ordered a specialized unit to assist the Fiscalía General de la República.
President Claudia Sheinbaum sent a diplomatic note to the United States on April 22 demanding explanations. No formal response from U.S. authorities has been received so far.
