text: The leader of a gang that attacked young girls in Sydney's southwest has been attacked by fellow inmates inside one of Australia's toughest prisons. Bilal Skaf was assaulted by three other inmates in the yard of Goulburn Correctional Centre on Friday. A Corrective Services statement confirmed a '33-year-old inmate' sustained minor head injuries and was treated in hospital before returning the same day. Sydney rape gang leader Bilal Skaf has been attacked by fellow inmates at Goulburn Correctional Ccomplex in NSW. He is pictured (in orange overalls) with his mother, Baria (right) inside Goulburn's Supermax prison on internal prison CCTV in 2002 when he tried to smuggle letters to his girlfriend out through Mrs Skaf . Bilal Skaf (left and right) was the leader of the rape gang which terrorised Sydney teenage girls on a four-week rampage before the 2000 Sydney Olympics for which he received a 46 year sentence and will be eligible for parole, if he behaves himself in prison and admits his crime, in 2033 . Gang rape leader Bilal Skaf pictured in the living room of his family home in Sydney's western suburbs posing with a firearm next to a photograph of his parents and siblings, including his younger brother Mohammed who was also convicted for the  rapes and is serving 32 years in a cell shared with Bilal . 'Three inmates have been segregated while the investigation continues,' Corrective Services said. In 2002, Skaf was sentenced to 55 years' jail for his part in a series of gang rapes in Sydney's southwest. Skaf was one of 14 mostly Muslim Lebanese Australians who went on a four-week rampage of raping Australian women and teenage girls in Sydney in the lead-up to the 2000 Olympics. The gang members, aged between 13 and 18 years, lured the girls from shopping centres and train stations and took them to parks and public toilet blocks. Daily Mail Australia previously reported that one of the victims was raped 25 times by a total of 14 men at Bankstown, in Sydney's west, in an ordeal that lasted six hours, during which the attackers subjected her to racist taunts. Skaf was aged 18 at the time of his rapes and is not eligible for parole until February 11, 2033. During the sentencing, Judge Michael Finnane described the rapes as events 'you hear about or read about only in the context of wartime atrocities'. In August that year, Skaf was moved from Sydney's Long Bay after fellow inmates threatened to inject him with HIV-infected blood they were planning to take from another prisoner. He spent time in the High Risk Management Correctional Centre inside the Goulburn prison complex, where he was caught in 2002 trying to smuggle letters out via his visiting mother, Baria, to his then girlfriend. They were caught and Mrs Skaf was banned from visiting her son for a time. Skaf was later moved to a secure section of the main prison at Goulburn and into a cell he shared with his brother Mohammed, who was also convicted of the 2000 gang rapes, and sentenced to 32 years.
