Police in South Africa have arrested four individuals, including two Mexican nationals, after discovering a multimillion-dollar drug manufacturing lab on a farm in the country's north, CNN reported. The South African Police Service (SAPS) and the Directorate for Priority Crime Investigation, known as the Hawks, raided the property in Groblersdal following reports of suspicious activity, according to a SAPS statement. Upon searching four structures on the farm, police discovered large quantities of chemicals used in the production of illicit drugs, such as acetone and crystal meth, with an estimated street value of 2 billion South African rand ($109.4 million). The four suspects arrested on Friday include the farm owner and two Mexican nationals. It is unclear whether the seized drugs were meant for the South African market or export.
