He told the press he received the last threat last week in the wake of an article head-lined "Mesic Governing Intelligence Underground" in which he claimed that in 2001 the president ordered the establishment of a parallel intelligence system that would answer only to him.
In the weekly's December 3 issue, Margetic wrote that an unlawful intelligence system was set up in early 2001 based on an agreement between Mesic and then Prime Minister Ivica Racan due to lack of trust in the then intelligence community, and that the system still had equipment and was able to supervise anyone without consequences.
Margetic also wrote that there had been attempts recently to ban and confiscate the weekly's latest issue by individuals from the parallel intelligence system.
He said that he was warned by telephone on November 26 that he had 24 hours to leave Croatia or face all sorts of consequences. He added he spent last weekend out of Zagreb.
Margetic claimed that over the last four years he had been interrogated more than 250 times, that his flat had been searched without a warrant three times, that he had been imprisoned four times, and that trumped up charges had been pressed against him on several occasions.
He said he had no one to complain to and that Justice Minister Vesna Skare-Ozbolt, whom he appealed for assistance, only told him that charges had been pressed against him.
Margetic concluded by saying that he had informed the Interior Ministry and the Counterintelligence Agency about secret services' locations but that they did not act on that.
