The country’s police chief announced on Sunday that Haitian authorities have arrested a man they say helped orchestrate the assassination of President Jovenel Moise.

Moise was killed Wednesday in his Port-au-Prince home, in an attack that has shaken a country already rattled by rampant violence and political instability.

The arrested suspect, identified as 63-year-old Christian Emmanuel Sanon, entered the country on a private jet in June, said Police Chief Leon Charles at a news conference, Police did not say what Sanon would be charged with, or what his motives may have been, beyond saying he arrived with “political intentions.”

Sanon is alleged to have been in touch with a Florida-based Venezuelan security firm to recruit 26 Colombian mercenaries and two Haitian-Americans. Their first assignment was to provide security for Sanon, but this mission is alleged to have evolved overtime.
