The Venezuelan, a 62 year old female, was arrested by the staff of the Customs Narcotics Unit after she arrived from Brazil via Dubai.
She is suspected to have swallowed 87 pellets of cocaine weighing more than 500g, the customs department said.
Customs officers produced the foreigner before the Negombo Magistrate who remanded her for 14 days.
She was later admitted to the Negombo hospital and is under customs supervision. (Colombo Gazette)
