Celtic scored four second-half goals as they increased their lead at the top of the Scottish Premier League to five points with a 4-0 home rout of Ross County.
After a goalless opening 45 minutes Celtic captain Scott Brown fired his side into the lead within a minute of the interval, opening the floodgates.
Gary Hooper headed home his 50th goal for Celtic in the 53rd minute before grabbing a double as he nodded home from close range 11 minutes later.
Replacment James Forrest wrapped up the scoring in the 70th minute with a fine individual goal.
The win, Celtic's fifth in a row, increases their lead at the top of the table to five over Inverness Caledonian Thistle who leapfrogged Motherwell following a 4-1 win over bottom of the table Dundee.
