POLICE on Monday arrested eleven men suspected of involvement in a cash heist which saw robbers shooting at security guards on the grounds of a primary school outside Pretoria earlier in the day. Pretoria police spokesman Captain Morne van Wyk said the search is continuing for another six suspects. Those arrested will face charges of armed robbery, attempted murder and being in possession of unlicensed firearms, and will appear in the Pretoria North Magistrates’ Court on Tuesday or Wednesday. Van Wyk said the suspects were arrested after police, with the help of a member of the public, found a house on a smallholding in Rooiwal, north of Pretoria, where the gang allegedly planned the heist.
