E/CN.4/1991/17 page 44 have been detained since April 1989. According to human rights lawyers the two security agencies responsible for the wave of arrests were the Joint Public Security Investigation Headquarters and the Agency for National Security Planning. It was alleged by these lawyers that many of the detainees were being held without warrants of arrests and were being prevented from meeting their relatives and lawyers. This led to allegations by detainees that they were tortured or ill-treated during their incommunicado detention. Reported cases of alleged torture or ill-treatment included the following: (a) Hwang Chong-su, one of a group of 15 striking workers in Changwon and Masan who, in April 1989, alleged that they had been tortured by police with electric shock batons. Hwang Chong-su allegedly required two weeks of hospital treatment; (b) Hong Song-dam, an artist and chairman of an artist federation in Kwangju, was arrested on 31 July 1989 for suspected contacts with a North Korean agent and for dissident artistic activity. He alleged having been severely beaten and deprived of sleep. It was later reported that a forensic pathologist, Prof. Lee Yun-song of the Seoul National University, had given evidence to the court supporting the torture allegations; (c) Chong Ha-su, an artist, was arrested on 4 August 1989. Together with two other artists - Cha Il-hwan and Paek Un-il - he was accused of having painted a mural in South Korea describing the history of the dissident movement in the country, and sending photographs of it to North Korea. Chong Ha-su claimed he had been tortured to force him to confess that he knew that Hong Song-dam (mentioned above) was an espionage agent; (d) Kim Chong-hwan, aged 23, a student at Koomkin University. On 9 August 1989 he was allegedly abducted by three or four men, who blindfolded and handcuffed him and then questioned him about the whereabouts of two other students. When he replied that he did not know, his abductors, whom he later claimed were military security officers, allegedly tied him to a tree, beat him and then threw him into a hole, shovelled earth on him and threatened to bury him alive. He was released several hours later. A spokesman of the Ministry of National Defence reportedly confirmed on 30 August 1989 that two military intelligence agents had participated in questioning Kim Chong-hwan, but denied the allegation that he had been put into a hole and threatened with being buried alive; (e) Suh Kyung-won, aged 53, an opposition member of the National Assembly who, on 20 December 1989 was sentenced to 15 years' imprisonment for spying. It was reported that following a visit to North Korea, which he himself reported, in June 1989, to the Agency for National Security Planning (ANSP), Suh Kyung-won was interrogated until 17 July and then transferred to Seoul Prison. It was alleged that during his interrogation period by the ANSP, which lasted for 24 days, he was banned access to his lawyers and relatives and was severely beaten and punched in the face and other parts of the body. In his trial Suh Kyung-won said that the ANSP had forced him to stay awake for 10 days and that the prosecution authorities did not allow him to sleep for more than two hours a day;
