E/CN.4/1992/17 page 68 later by the Judetul Bihor Localitatea Oradea Unitatea Institute stated that he had been beaten and that would require two or three days's medical treatment. 193. In a letter received on 4 December 1991, the Romanian Government replied that Mr. loan Gug had never been arrested. The Government indicated that, on 19 December 1990, the Bihor Democratic Alliance had organized a peaceful demonstration for which permission had been granted and that it ended at 7 p.m. Afterwards, several participants in the demonstration went to the centre of town in front of the Mayor's Office where they brought the traffic to a halt and aroused the anger of many of the citizens. The police officers took the necessary steps to remove the participants and asked some of the leaders, including Mr. loan Gug, to go to police headquarters for identification purposes. Mr. loan Gug was fined 500 lei - a civilian penalty. Mr. loan Gug then took his case to the Oradea military prosecutor and submitted a medical certificate which stated that he had been beaten up and that two or three days' medical treatment was necessary. After hearing Mr. Gug, the military prosecutor realized that he was unable to provide any information or evidence to identify the persons who attacked him. Under the circumstances, despite the efforts by the military prosecutor to conduct an inquiry and since Mr. Gug has gone abroad and has not returned, the case has been closed. Urgent appeals 194.
