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

Police have previously said a group of at least 28 people are suspected in the killing. At least 20 of those suspects have been detained, including two American nationals. Three suspects have been killed, while a mass manhunt is underway for the five suspects still on the loose.
