The arrests, made on Tuesday, are unusual in a country where police and military largely operate with impunity. Among those detained are a police captain and two sergeants. They have not been charged. The killings occurred on September 10 in Santiago de los Caballeros, one of the Dominican Republic’s biggest cities. Police have accused the suspects of opening fire on officers first, adding that the victims were members of a gang suspected of kidnappings, drug trafficking and contract killings. However, friends and family have disputed police accounts, noting that one of the suspects killed was a well-known barber in the community. The killings sparked protests, and human rights groups demanded an investigation. (Jamaica Gleaner)
