Johannesburg ( CNN ) -- Three of four minors accused of taking part in a brutal videotaped gang rape of a teenager will face full prosecution , a spokesman for a South African court said Wednesday . The boys appeared in court Wednesday -- along with three others who are not minors -- to apply for bail . The seven suspects are between the ages of 13 and 19 . A bail hearing will be held May 3 for the minors and June 20 for the adults , said the spokesman , Mthunzi Mhaga . It is unlikely that the suspects , accused of a crime that has shocked many in South Africa , will be granted bail , officials have said . An eighth suspect -- a man who was found with the victim -- is scheduled to appear in court on May 4 , court officials said . The images of the assault of the 17-year-old girl , believed to be mentally ill , swept across the Internet last week and touched a nerve in South Africa . The shocking footage shows the girl pleading for her attackers to stop , and it has some activists saying it is an example of the country 's problem with rape . The girl went missing on March 21 . Police suspect she was kidnapped and turned into a sex slave . The cell phone video of her gang rape surfaced and went viral among schoolchildren in Soweto , a vast township near Johannesburg . The Daily Sun , a local tabloid , alerted police about the attack after a concerned mother whose daughter was watching the video handed it over to the newspaper . Police embarked on a search for the girl and the people in the video . Eight suspects have been arrested and charged with kidnapping and raping the teen . Seven of them were seen on the video ; the other was a 37-year-old man found with the girl last week . A woman is raped every 26 seconds in South Africa , according to local aid groups . More than 60,000 cases of sexual assault were reported in the year to March 2011 , down from 70,000 in 2008 , police said . Women 's rights activist Lisa Vetten says in the province of Gauteng , where Johannesburg is located , one in every five rapes is a gang rape . `` Rape is a young man 's crime , '' she said . `` It 's a bit of a performance for them , showing off to each other how macho they are . We need to teach our young men that you can be masculine in ways that do not involve violence and degrading women . '' The mother of the 17-year-old has said this was not the first time her daughter has been raped . She was raped in 2009 and 2010 , and authorities have done little to address the issue in the past , the mother said . `` It 's 2012 now , and I 'm still waiting for DNA results , '' she said . After the girl was found and as the news of the video emerged , the government placed her in a safe house -- a place where she can attend school and socialize in a secure environment . `` They are coming now because things have turned out this way , '' the mother said . `` They should n't pretend as if they have been standing up for me . They never stood up for me . ''
Seven girls , aged 13 to 19 , are waiting for bail . Six people have been arrested , accused of kidnapping and rape . The gang - rape video went viral and shocked South Africans . Mother says her daughter was raped in 2009 and raped .
