Among these objectives is the incorporation of the Catalan body Intelligence Center against Terrorism and Organized Crime (CITCO).
The vacancy will be assumed by Pere Ferrer, until now chief of staff of the Catalan interior advisor, Miquel Buch.
"I appreciate the good work that Andreu Martínez has done at the helm of the Mossos," says a message posted on Twitter by Buch, who took the opportunity to publicly welcome and wish luck to Pere Ferrer, the successor in office.
At the moment it is unknown if behind the resignation there are hidden strategic differences within the independence movement on the direction of security management in the face of the important events that Catalan politics will experience in the coming days.
In the first place, this October 1 will be two years of the referendum of October 1, 2017.
In addition, it is expected that the Supreme Court will issue its judgment against the twelve independence leaders accused of rebellion, embezzlement, sedition and disobedience by the convening of the consultation in the first half of October.
Predictably, these two events will open a new cycle of protests by the independence movement.
In addition, the new director of the Mossos will have to manage the crisis resulting from the alleged emergence of independentist sectors willing to carry out terrorist actions, an issue that on September 23 took seven detainees in Barcelona.
The resignation of Andreu Martínez is the third relief at the head of the political headquarters of Mossos in just over two years.
In 2017, on the eve of the celebration of the aforementioned referendum, the then director of the Mossos, Albert Batlle, resigned alleging "political motives."
His successor in office, Pere Soler, was dismissed in October of that same year when the Spanish Government decided to apply Article 155 of the Constitution to intervene in Catalan institutions in response to the territorial crisis generated by the referendum.
Pere Soler is currently awaiting trial for the alleged commission of a crime of rebellion for allegedly acting as a "key piece" of the Catalan independence plan to force a break with Spain in autumn 2017.
In July 2018, once the Catalan self-government was reestablished, the appointment of Andreu Martínez, who now resigns from the management of Mossos, one of the hottest chairs within the skeleton institution of Catalonia was made.
