Police are searching for 22-year-old Siafolau Siafolau in connection with the seizure of more than 525 kilograms of cocaine off Lancelin, Western Australia, earlier this month.

Two other men were arrested in Sydney and two more in Perth this month as part of the ongoing drug trafficking investigation, highlighting continued efforts to bring all involved to justice.

Authorities are urging anyone with information on Siafolau’s whereabouts to call 131 444, and warn that helping him evade arrest could result in charges.

Investigations indicate Siafolau traveled to Perth in late October and was part of a group that repeatedly retrieved cocaine at sea before allegedly flying back to Sydney on November 4.

A joint Western Australia crime taskforce, comprising the AFP, WA Police, and Australian Border Force, has appealed for public help to locate him, with a Perth court issuing a warrant for his arrest.

The seized cocaine is valued at about $170 million on the street, according to police estimates.

Police allege Siafolau was involved in a plot to import and distribute the cocaine, which was found on November 6 tied to flotation drums about 30 kilometers offshore from Lancelin and linked to the livestock carrier Al Kuwait.
