In July 1984, the local FBI informed their counterparts in the states of the Cuban involvement, surprising Millan and Duffy, who had assumed that Gerena could be in Canada based on a trip mentioned by an ex-girlfriend and which had led to a collaboration with the Mounted Police and a search there. On January 25, 1985, the EPB attacked the Federal Court Building with a bazooka, in protest to the presence of an American military recruit center within it. On April 2, 1985, the EPB criticized that people uninvolved in the heist were being pressured in the grand jury investigation, and sent a banknote taken during the heist as proof that the group was responsible for it. Following a threat of retaliation, the subpoenas issued to third parties were dropped.
