Hawks spokesperson Brigadier Hangwani Mulaudzi said after the bust, that acting on a tip-off, the pair were nabbed when their delivery van, which was destined for the Eastern Cape from Gauteng, was stopped and searched just outside Bloemfontein.
Just underneath the loading zone of the vehicle, the Hawks discovered a self-made compartment with nine bags with 20 plastic packets containing mandrax tablets to the value of R12 million.
