The Prosecutor's Office said in a statement that Prates, a former member of the Yugoslav State Security Service (SDB), was charged with having given his superior at the time, Josip Perkovic, or some other leading SDB official, spare keys to his printing office in Wolfratshausen, where Djurekovic, who had emigrated to Germany in 1982, printed his books.
Prates also provided information on when Djurekovic would be in the printing office. The indictment alleges that Perkovic or some other persons then gave the keys and relevant information to two unidentified perpetrators, after which Djurekovic was shot dead on 28 July 1983.
The indictment alleges that Prates, who has been living in Germany since 1971, was familiar with plans to kill Djurekovic and that since he started working for the SDB in 1975 he had provided information on the activities of Croatian political emigrants.
Prates was arrested in July this year with another person, who was released shortly after the arrest, and has been in police custody in Munich since. In late October the German Federal Criminal Office (BKA) issued an international warrant for the arrest of Josip Perkovic in relation to Djurekovic's murder.
