Catalonian protesters rejoiced outside of the CUP (Candidatura d'Unitat Popular) headquarters in Barcelona, after Spanish security forces stood down and departed from an eight hour standoff, Wednesday. Tensions rose between police and Catalan protesters throughout the day following the security forces' foiled attempts to enter the premises without a court order. The police left at 20:00 (GMT... Еще) and no arrests were reported. Spokesperson of the National secretariat of the CUP Nuria Gibert explained that it was unclear why the police operation was being carried out. «They have denied to speak or to return so much as a word, so at this time we do not know yet what they want, or what they are looking for», she said. Deputy Leader of the CUP, Benet Salellas, has reportedly announced that a committee of legal experts has been established to seek answers for the reason police surrounded the building. Catalan citizens will vote in an upcoming historic independence referendum on October 1, in a ballot that has been deemed illegal and unconstitutional by the Spanish Supreme Court.
