POLICE arrested four men on Thursday night in connection with the murder of six men who died after being locked in a meat cooler truck in Vereeniging. Gunmen overpowered the six men of the JP Meat enterprise last week and locked them in a cooler truck where they suffocated. The robbers fled with a truck full of meat, R20000 in cash, a gun and a cellphone. Vaal Rand police said on Friday that the suspects are expected to appear in Vereeniging’s Magistrate’s Court on Monday.
