  FOUR men who stripped, whipped and beat a teenage hostage for more than six hours have walked from the District Court with suspended sentences. Judge Michael Boylan yesterday agreed, with great hesitation, to release the men, whose crimes were prompted by an alleged racial slur.  His decision was made at the urging of the Office of the Director of Public Prosecutions, who said the men should be released.  Judge Boylan said the 17-year-old male victim had suffered extreme humiliation and degradation at the hands of the group. Navnett Arora, 22, of Morphettville, James Van Gelder, 22, of Clarence Gardens, Nathan Charles Chetcuti, 24, of Walkley Heights and Steve Karapetis, 21, of Happy Valley, pleaded guilty to offences including kidnapping and assault.  In April, 2004, Arora attacked a 17-year-old boy he had thought called him a black c.... Though the boy claimed he was innocent, Arora called the three co-accused and the boy was then forced into Van Gelder's car.  For the next six-and-a-half hours the group drove the boy around, beating and slapping him across the face.   On one occasion, he was stripped naked and beaten with a belt - he was whipped a second time while strapped to a tree. Arora called the teen's mother and demanded a $5000 ransom, then went to their house and stole a stereo.   The youth was eventually dumped at a petrol station.  In sentencing, Judge Boylan said Arora - who was born in India - had endured constant racism since arriving in Australia. That abuse, however, was no excuse for his bizarre behaviour.  He imposed suspended sentences of four years and three months on Arora, three years on Karapetis and 15 months on Chetcuti. Van Gelder, who also pleaded guilty to an unrelated offence, received a suspended term of four years, 11 months.    Unbelievable aye! The race card seems to be a get out of jail free card.
