Police Public Relations Officer Aniel Innocent told St. Lucia News Online today that the suspects were released over the weekend.
However, Innocent said one of the men were charged with the possession of marijuana.
SNO understands that a notorious criminal was among the three men held in custody in connection with the July 18 armed attack.
It is alleged that the man could have been the mastermind for several other robberies over the years.
Reports are that armed men stormed the accounts office of the hotel and held up a female employee.
No one was injured in the attack and no cash was stolen.
Police nabbed the suspects minutes after the crime.
