A top security official of slain Haitian President Jovenel Moise was arrested by police on suspicion of involvement in the assassination plot, his lawyer said on Tuesday, as another aide’s apparent account of the event was leaked on social media.

Presidential Security Coordinator Jean Laguel Civil was arrested on Monday, lawyer Reynold Georges told Reuters, nearly three weeks after Moise was killed on July 7 in the middle of the night at his private residence in Port-au-Prince by a group of more than 20 mostly Colombian mercenaries.

Civil’s arrest followed the earlier detention of another senior member of Moise’s security detail, Dimitri Herard.

On Tuesday, a July 10 memo signed by Herard setting out the events of the assassination night was leaked on social media. Reuters could not immediately confirm its authenticity.
