TORONTO - Four people have been charged after border officials at Toronto's Pearson airport say they seized 37.5 kilograms of cocaine.

Canada Border Services Agency says officers found the drugs hidden in three different shipments of machine parts that originated from Panama.

Three men and a woman, all from the Toronto area, were arrested between Aug. 7 and Aug. 20 after a multi-agency investigation.

Philmore Jarvis, 47, Michelle Maraj, 36, and Wilson Jaramillo, 37, all from Mississauga, and Vernon Bouillion, 38, of Milton, face charges including importing a controlled substance and possession for the purpose of trafficking.

Jarvis, Jaramilo and Bouillion are in custody while awaiting a court appearance scheduled for Thursday.

Maraj is out on bail and her next court appearance is on Sept. 12.
