Haitian police on Sunday arrested someone they suspect was a mastermind behind the assassination of President Jovenel Moise last week.
Authorities accuse Christian Emmanuel Sanon of hiring mercenaries to oust Moise and plotting to then install himself as president
"Sanon arrived in Haiti on a private plane with political objectives, according to our information...He had contacted a company specializing in security to recruit some bandits, and arrived in Haiti at the beginning of June, accompanied by some of them. They were initially supposed to guarantee his security," said National Police Chief Leon Charles.
Police say what was once a mission to protect Sanon later changed to replacing the president.
Following the killing at Moise's home last Wednesday, police arrested a group of Colombians and two Haitian Americans
The authorities said it was a commando unit, armed and trained.
According to the Miami Herald, the Colombian suspects said their mission was to arrest Moise, not kill him.
Police later confirmed Sanon had given one of the suspects an arrest warrant for the president.
Although the details of the alleged plot are still unclear, along with Sanon's motives.
There could, however, be an American connection.
The Miami Herald also reported that some of the Colombians claimed to have been hired by a Miami-based security firm.
And public records show a man with the same name as Sanon has worked as a doctor in Florida.
Although no confirmation yet on whether it is the same man.
The assassination has plunged poverty-stricken Haiti into chaos.
The government has appealed to the international community for help.
On Sunday, the Pentagon said experts from the FBI and Department of Homeland Security would be travelling to the country to help with the investigation.
