The protesting group, which was made up of Umkhonto we Sizwe military veterans and the Azanian People’s Organisation members, forced its way into the building, damaging doors, windows and equipment.
Warning of scenes similar to the Marikana tragedy, the group said it would not back down until government addressed its demands.
These included the fulfilment of promises it claimed the ANC made 11 years ago, including government subsidies for their contribution to the struggle and to be integrated into the police and military.
The protesters said they had letters from government to prove their claims.
The remaining 70 protestors who had not been arrested said they would not stop until they too were taken into custody.
The group added that it would not be voting nor campaigning for the ANC ahead of the 2014 general election. – EWN
