However, soon after he signed with USL-2 side Wilmington Hammerheads FC, a team in the 3rd tier of American league soccer.
In June 2009 he went on a trial with Swedish side GAIS and on 8 July the club confirmed signing of Angus. Angus made his debut for GAIS against Halmstad BK on 12 July 2009. He came off the bench in the 81st minute and scored the equalizer for GAIS in the 90th minute of the match. Angus spent time training with West Ham United at the end of the 2011 Allsvenskan season. GAIS finished in last place and were relegated from the 2012 Allsvenskan. After their relegation the club announced that four of the players who were under contract would be allowed to leave for free, Angus being one of them. As he was unable to find a new club during the winter transfer window he remained at GAIS for the first half of the 2013 Superettan season before eventually leaving at the end of July.
