Bolivia's Public Ministry intensified search efforts for Maximiliano Oscar Martínez, a 30-year-old official of the Argentine Federal Police reported missing in the border city of Villazón since 11 September, according to lapatria.bo.
The investigative actions, coordinated with Argentine authorities and various units of the Bolivian Police, were concentrated in Villazón, where on the night of 11 September an operation was carried out to search and inspect several nightclubs and brothels.
According to the case background, there are indications that Martínez was present in those establishments during the nights of 8 and 9 September, dates prior to the loss of contact regarding his whereabouts.
The Departmental Prosecutor of Potosí, René Walter Cáceres Juchani, detailed that the work is being carried out jointly with representatives of the Argentine justice system, highlighting the participation of the Prosecutor of La Quiaca in the interventions carried out in the Bolivian municipality.

The General Prosecutor's Office (FGE) stated that tracking efforts will be maintained actively and continuously in Bolivian territory, whilst strengthening the exchange of information and inter-institutional cooperation with Argentine authorities to clarify the facts.
