The two were convicted and sentenced in the high court in Middelburg after a video surfaced of them forcing Victor Mlotshwa into a coffin.









They were convicted of assault with the intention to do grievous bodily harm, kidnapping, attempted murder, intimidation and defeating the ends of justice in 2016.









Oosthuizen was initially sentenced to 11 years' imprisonment and Jackson to 14 years.









However, in December last year, the Supreme Court of Appeal (SCA) amended their convictions and sentences, setting aside their attempted murder and intimidation convictions.









Justice and Correctional Services spokesperson Crispin Phiri says the two will remain behind bars.









“Following a review of the processes conducted to grant the two set individuals parole, we have established that a proper victim offender dialogue process was not followed. As such the department has decided to revoked the decision to grant these two individuals parole.”









The two were placed on parole in February.
