Third arrest in alleged rape of boy, 15, at Magill A THIRD man has been arrested over the alleged sexual assault of an intellectually disabled teenage boy last month. Detectives from the Sexual Crime Investigation Branch have arrested a 43-year-old man from Blakeview and charged him with rape and indecent assault. He has been refused bail, and will appear in court on Monday. Two other men from Magill, aged 55 and 43, appeared in Adelaide Magistrates Court on Friday on charges including unlawful sexual intercourse. Police have laid further charges of rape and indecent assault against the men, as well as a charge of aggravated endangering life against the 43-year old, who is HIV-positive. The offences will be alleged to have occurred between 22 December 2012 and 31 January 2013 in Magill and other places in South Australia. The court heard the 15-year-old victim was taken to a Magill home on January 30 before being tied up with rope, blindfolded and repeatedly raped. The alleged victim has the cognitive function of a 12-year-old, the court heard. All three accused will face court again this week.
