According to the information of the department, Madrid had to take such measures in connection with the forthcoming referendum, which will be held on October 1.
Madrid appointed the new head of the Catalan police Diego Perez de los Cobos.
Thus, the central authorities want to improve the coordination of law enforcement agencies to prevent an illegal referendum.
The current Minister of Internal Affairs of Catalonia, Joaquim Forn, said that they refuse to comply with Madrid's order.
Local authorities and the police will also not perform installations in the center.
However, the Spanish Interior Ministry maintains that an additional contingent of police and new appointments are made in order to prevent further terrorist attacks in Barcelona, ??as it was months ago.
As reported in "URA-Inform", the head of the Spanish government, Mariano Rajoy, earlier called on the Catalans not to hold a referendum on independence planned for autumn.
