Nathan Shaw and Scott Allardice earned Inverness a 2-0 win over Arbroath in the cinch Championship.
Early efforts from Caley Thistle’s Sean Welsh and Arbroath’s Lewis Banks were as good as it got in a goalless first half.
But Shaw opened the scoring eight minutes after the interval, converting Jay Henderson’s cross after a swift counter-attack.
Billy Mckay went close from Shaw’s cross and it was 2-0 through Allardice’s 78th-minute penalty.
Henderson again played a key role, winning the spot-kick, but he was shown a straight red card a minute later for a foul on Michael McKenna.
