A hat-trick from Iain Vigurs helped Inverness thump Dunfermline 5-1 and move joint-top of Betfred Cup Group C.
Vigurs gave the visitors the lead after a quarter-hour and even though Andy Geggan pegged them back, Vigurs' second put them ahead at the break.
Billy King extended Caley Thistle's lead in the second half and Vigurs completed his hat-trick with a well-placed header.
Carl Tremarco's late fifth put the icing on the cake for a potent Caley Jags side.
Caley Thistle led with 16 minutes on the clock....
