The national police of Haiti, on Sunday, disclosed that the mastermind in the assassination of President Jovenel Moise has been arrested.
The police chief, Leon Charles at a press conference disclosed that a Haitian doctor living in the U.S. state of Florida was arrested.
It was disclosed that the suspected killers called him after the attack and evidence was found in his flat.
It was gathered that the accused doctor recently arrived in Haiti on a private plane to seize the presidency.
The 63-year-old doctor allegedly hired Colombian mercenaries through a private Venezuelan security firm based in Florida.
The doctor is the third U.S. resident of Haitian origin and the 21st person overall to be detained as a suspect in the case.
The other two also reportedly lived in Florida.
Police noted that 26 Colombian mercenaries were involved in the murder overall, three were killed, 18 suspects were in detention and police are seeking the remaining five.
High-ranking U.S. officials who are expected to help with the investigation met with Charles on Sunday.
Moise, 53, was shot dead at his residence in Port-au-Prince in the early hours of Wednesday, while his wife Martine was seriously injured and taken to Florida for treatment.
The reasons for the attack remain unclear.
