This was confirmed by Samoa's acting police commissioner, Papalii Monalisa Keti.
However she said the Attorney General, Lemalu Herman Retzlaff, is reviewing the file before the police will carry out the normal procedure for filing the charges.
Since last night, police have arrested two suspects in relation to the case: Malele Atofu Paulo, also known as King Faipopo; and Lema'i Faioso Sione.
The pair are in police custody.
Police have released few details on the alleged plot, which came to light two days ago.
