2009 – The dispute over British-claimed territorial waters gained prominence with deliberate incursions by Spain, triggering angry headlines in the UK tabloid press. In December 2009, four armed Civil Guard officers were detained after three landed in Gibraltar in pursuit of two suspected smugglers, who were themselves arrested. The Spanish Interior Minister Alfredo Pérez Rubalcaba personally telephoned Chief Minister Peter Caruana to apologise, stating that there were "no political intentions" behind the incident. The Chief Minister was prepared to accept it had not been a political act. The Spanish officers were released by the police the following day, who said that "Enquiries established that the Guardia Civil mistakenly entered Gibraltar Territorial Waters in hot pursuit and have since apologised for their actions."
