At least six Navy officers and policemen have been arrested in the Dominican Republic as part of an ongoing investigation into the drug-related killings of seven foreigners, the associated press reported.
Navy Vice-Admiral Julio Cesar Ventura said Sunday that he seized the suspects' weapons so ballistic experts can determine whether they were used in the Aug. 4 massacre.
Police say a Navy captain arrested with cocaine packets five days later had ordered the shootings. The victims were found in a sugarcane field with their hands tied. The majority of them were from Colombia.
A judge on Saturday ordered three Navy officers to 18 months in jail while the investigation continues. Another nine people also have been arrested, including two businessmen.
