A 33-year-old woman was arrested at Cape Town International Airport for the possession of cocaine.
Police spokesperson Lieutenant Colonel Andrè Traut said an intelligence-driven operation was conducted on Wednesday and "the suspect who entered our ports on a flight from Luanda was placed under observation and apprehended after it was discovered that she had swallowed 100 bullets filled with cocaine".
The woman was detained and admitted to a medical facility where the contraband was collected.
"The exact value of the drugs is yet to be established but is estimated at a significant amount.
"Once charged, the suspect is due to make a court appearance in Bellville Magistrate's Court to face a charge of dealing in drugs."
