The AMP is under investigation for allegedly mixing with martial arts gang members before its political rally in Ainaro earlier this month.
National Police Commander Operational Hendrique da Costa said any political activity attended by martial arts leaders would be shut down and party members arrested.
“If PNTL find some ritual activities in the campaign we will arrest them because it’s against the law,” he said
Under Timor-Leste law 5/2017, martial arts gangs are banned due to their heavy involvement in crime, political provocation and violence.
