claims man was wronglly arrested A young Australian man has been allegedly tortured in a South Sudan military prison after his supporters say he was wrongly arrested during ethnic clashes on a trip to visit his family. Manyang Maker Tulba, 22, was one of 100 people taken into custody in February during fighting in Rumbek, in South Sudan's north. But Magang Chol Mathei, the chairman of the Rumbek Youth Union in Australia, claims Mr Tulba, a university graduate who was born in South Sudan but moved to Perth in 2003, was not involved in the violence but merely witnessed the clashes. He said Mr Tulba was in a house near where the violence unfolded and was swept up in the arrests. Mr Tulba's mother, who was with him at the time, also has been arrested and is being held in a separate prison, according to reports from Sudan. Mr Mathei told the Sudan Tribune that Mr Tulba had not been allowed visits from relatives, lawyers or human rights officials during his incarceration. He had also been tortured, Mr Mathei claimed, saying Mr Tulba was"innocent" and there was "no need for him to be detained and tortured while he was not there where the fighting was occurred [sic]." There is no any protection at all. I am concern about his welfare and his future [sic]," he said. He urged youth leaders in the area to approach the governor to ask him to free prisoners who were not involved in the recent violence. Mr Tulba was one of about 100 young men from the Kok section of the Dinka tribe who were arrested during the clashes in February. Mr Tulba graduated from Perth's Edith Cowan University in 2011 with a bachelor of criminology and justice. The Department of Foreign Affairs and Trade has been contacted for comment.
