Correctional Services said that “matters are under control” at Johannesburg’s Sun City Prison on Wed.
Kano Pillars, the Nigerian Premier League champions, are on a tour of South Africa in preparation for the coming CAF Champions League.
The continental competition kicks off next month and the Nigerians take it so seriously that they have lined up four local clubs and an Angolan team to help prepare for the gruelling road ahead.
The first match is against Mamelodi Sundowns - who themselves have a Confederations Cup campaign to contend with - this afternoon at Sundowns' training grounds in Chloorkop at 3.30.
Pillars will then play Moroka Swallows on Saturday at Germiston sports grounds, Primero Augusto at Tshwane's High Performance Centre and the last match will be against Ajax Cape Town at Ikamva sports grounds in Cape Town.
Surprisingly, Absa Premiership champions SuperSport United do not feature in this line-up. Pillars' first Champions' League match is against Chad club Elect Sport at home on February 1.
Tour organiser Mohammed Lawal said the Nigerians - who have brought 30 players and 12 officials - were based in Sandton.
He said everyone was expecting Pillars to do well in the continental competition. Pillars' danger men are attacking midfielder Ahmed Garba and strikers Austin Apehe and Kampo Mohammed.
