At least three Haitian police officers were killed in the capital by the Ti-Makak gang, which subsequently circulated the images on social media.
The anti-gang unit police officers conducted an operation in the area where the armed group operates, and then gang members kidnapped at least one of the dead and took the weapons.
In the same region south of Port-au-Prince, two journalists were killed last January, and former senator Yvon Buissereth, whose body was burned along with an escort.
The armed group became known last year when citizens began using the area where they are based on reaching the southern departments after other gangs blocked access through Martissant.
The murder occurred during nationwide protests against the fuel price increase announced by Prime Minister Ariel Henry on Sept. 12.
According to the head of government, the state must stop subsidizing fuel to fund social programs for the most vulnerable.
Still, that rationale did not convince the hundreds of citizens who took to the streets and blockaded the capital.
The Haiti crisis has worsened since President Jovenel Moise’s assassination last year.
The crime remains unsolved.
The institutional crisis triggered by the assassination has been exacerbated by a surge in violence, hundreds of deaths, and kidnapping victims at the hands of armed gangs, economic recession, and uncontrolled migration.
