Striking plastic industry workers allegedly vandalised property on the Gundle Plastics Group premises in the East Rand. Watch.
Constable KM Mabunda from the Germiston police station said last Tuesday striking employees forced their way through the gate at around 14:00 and assaulted two workers.
He said 30 vehicles were damaged, three of which were set alight.
Constable Mabunda added that part of the reception area was burned and goods - including four cellphones, two laptops and several wallets - were stolen. The damage is estimated to amount to R2m.
No arrests have been made, but an investigation is underway.
A case of malicious damage to property was opened.
In October, the Labour Court in Johannesburg ruled that the National Union of Metalworkers of South Africa's strike in the plastics sector was legal and that the employers in the sector could not undercut the union and its members' right to strike.
Now in its ninth week, striking plastics employees say their protest action is against poor pay and racism in the industry.
