A Samoan opposition MP Olo Fiti Vaai has called for a commission of inquiry to investigate the police ministry, saying it is in a mess.
This follows Monday's arrest and suspension of the police commissioner on charges including inciting murder.
Olo told the Samoa Observer that such an inquiry was long overdue as internal fights between police officers had been going on for a long time.
He warned that the division within the police force is something that should not be taken lightly.
Olo likened the situation to that of the late 1990s when a cabinet minister was assassinated as a result of a conspiracy between two fellow HRPP members.
