The American Federal Police (FBI) arrested in Florida four more suspects related to the assassination of the president of Haiti Jovenel Moise in 2021.

Moise’s death has led to a power vacuum in the Caribbean country and strengthened the gangs that act as de facto authorities in much of the capital, Port-au-Prince.

Eleven people are being held today in the US on charges related to the organization and execution of the assassination of the Haitian president. Three of the four new arrestees, Antonio “Tony” Indriago, owner of Counter Terrorist Unit Security, or CTU, Archangel Pretel Ortiz, manager of CTU affiliate Federal Academy LLC, and Walter Veidemilla, the head of Worldwide Capital Lending Group accused of supporting the conspiracy to kidnap or kill the president. The fourth, Frederic Bergman, is accused of conspiring to smuggle bulletproof vests that would have been used by the Colombian soldiers who allegedly executed Moiz.

The investigations focus on weapons, bulletproof vests and the financing of the operation.

Indriago is an American-Venezuelan businessman while Pretel Ortiz is an American-Colombian. Both are being held in South Florida, according to the Justice Department. Veidemila, who is an American citizen, loaned more than $170,000 to CTU Security to finance its operations in Haiti.

Indriago’s attorney told The New York Times that his client will plead not guilty in court where he will be arraigned later today to determine whether he will be released on bail.

Gangs in Haiti have expanded their influence since the president’s assassination. Much of the country is not controlled by the government, and clashes with the police have become routine. In October the United Nations proposed sending a “rapid action force” to Haiti to deal with the escalating violence that has killed hundreds of people and displaced thousands.

The three-day meeting of the leaders of the Caribbean countries (CARICOM) starts tomorrow Wednesday, where one of the main topics is expected to be the situation in Haiti.
