Police spokesman Garry Desrosiers told the press that none of the new suspects had been arrested yet, and did not make clear the role they played in the assassination.
Twenty other officers are being detained at the National Penitentiary, but no charges have yet been brought against them.
At the end of January, suspects James Solages, Joseph Vincent, Emmanuel Sanon and Colombian Germán Rivera García, who are accused of plotting to kidnap Moïse in June 2021 and then orchestrating his assassination, were extradited to the United States.
Nearly two years after the incidents, the investigation is at a standstill in Haiti, despite calls from international bodies to carry on with the probe.
