Alberto Pons, the former president of the Balearic Ports Authority, has told the National Police that it was he who ordered the installation of microcameras in the president's office.

The police were called in to investigate the discovery of two state-of-the-art microcameras in the ceiling of the office of the current president of the Balearic Ports Authority, Joan Gual de Torrella. The cameras were capable of recording conversations as well as movements. One was focused on the office in general; the other was directed towards the table used for meetings.

Gual had suspected that he was being followed, quite probably by private detectives. The ports authority therefore brought in counterespionage specialists. They undertook a sweep of the office and found the cameras. Two other rooms were examined - the director-general's office and the boardroom - but no devices were found.

Pons was Gual's predecessor. He says that the cameras were installed in the autumn of 2013. He had ordered this because he was concerned about security and that someone might have been entering the office and looking at his documents. He explains that private detectives would periodically download the contents of the cameras' hard disc and that they never found anything suspicious. "I forgot about the cameras, until now," he says, adding that there was no formal transfer of powers to Gual, so he was unable to tell him about the cameras.

The police are for now continuing their investigations.
