Large quantities of chemicals used in the manufacture of illicit drugs, such as acetone, and methamphetamine with an estimated street value of 2 billion rand ($109.5 million), were found, the statement said.
“What makes it different from others is the involvement of Mexican citizens,” said Katlego Mogale, national spokesman for the Hawks, an elite police unit that took part in the raid.
