even though the police operations were not notified in advance to the autonomous police force of catalonia, mossos d'esquadra, as soon as people started gathering around the catalan economy department, civil guard requested the intervention of mossos. the civil guard agents involved in the raid made 6 calls for help to mossos during the day. the first request for help was at 9:14 am with the subject: "urgent - request for support to mossos" with the goal to force people to move 40 meters away from the building. mossos did not intervene alleging that might cause public disorders and that the demonstration was being peaceful and authorized. instead, anc volunteers created a human corridor so the access to the building would not get blocked. workers of the department of economy hung catalan and european union flags in the balconies of the building as long as the raid lasted. mossos alleged they were not notified in advance about the raids, so they couldn't prepare a police operation to keep demonstrators far from the building. at midday, the civil guard notified mossos they would end the registries around 20.15, but later stated they would be delayed for hours due to computer problems. mossos considered there was a situation of risk, but discarded using crowd-controls units until later in the night when most demonstrators already left.
