Police will be holding a press conference later today in Perth regarding drug seizures related to the suspicious boat that came into Geraldton earlier this month.

It's being reported by ABC that up to 200kg of meth has been seized from an international drug syndicate following raids on homes in Perth on Saturday, in connection with the men arrested.

Details of the case and those charged has been suppressed by the courts up to now.

Around midday on 2 May 2016, some Everything Geraldton readers spotted the suspicious boat in Geraldton's port, and a number of men, pictured below, who according to onlookers "appeared foreign" were seen being questioned by authorities, before being taken away.

Police later confirmed 8 Chinese men with no entry visas for Australia had been arrested and placed in immigration detention, but would not comment on their investigations.

The boat remained in Geraldton's port for several days while it was searched and contents from the boat removed.
