Attorney-General Jose Manuel Maza called on Monday on the leaders of the Catalan independence movement to be called to testify in court, DW reported.
Under Spain's legal system, the request goes to a judge for consideration.
Rebellion, sedition and missue of public funds can carry punishments, respectively, of up to 30, 15 and six years in prison under Spanish laws.
Maza said he would ask the judges for preventive measures against the officials, but didn't specify if those included their immediate arrest and being sent to jail while awaiting trial.
