A group of seven foreigners and one local were apprehended by Haitian authorities amid violent unrest in the nation. The suspects, who allegedly have military backgrounds, were equipped with an arsenal of guns and even drones.

The group was apprehended on Sunday in the Haitian capital city of Port-au-Prince, shortly after leaving the Bank of Haiti, local newspaper Le Nouvelliste reported.

The suspects, traveling in two vehicles without license plates, were well-equipped with military-grade weapons, body armor and even drones. They had several sets of plates with them, but it was unclear if they were genuine or fake. The individuals initially refused to leave their vehicles, reportedly claiming they had been working “for the Haitian government.”
