Haiti’s chief public prosecutor has asked the judge overseeing the investigation into the assassination of President Jovenel Moise to charge Prime Minister Ariel Henry as a suspect and ordered migration services not to let him leave the country.

Prosecutor Bedford Claude in a letter said phone records showed Henry twice communicated with a key suspect in Moise’s killing on the night of the crime on July 7.

That suspect, a former justice ministry official whom Henry has publicly defended, is now on the run.

In a letter to the country’s Migration Services, Claude wrote Henry should be “forbidden from leaving the national territory by air, sea or road due to serious presumption relative to the assassination of the president.”

A member of the prime minister’s communications office said it did not have an immediate comment.

Haiti’s Office of Citizen Protection demanded on Saturday Henry step down and hand himself over to the justice system.

Henry retorted on Twitter that he would not be distracted him from his work.

Moise was shot dead when assassins stormed his private residence in the hills above Port-au-Prince, plunging the impoverished Caribbean country deeper into turmoil and a political vacuum.
