Celtic continues to pick up points at a 0 win over Hibernian at Easter Road on Sunday.
The Bhoys have now won an astonishing 14th-straight league match to improve to 68 points on the season. Sunday's road win extended their lead atop the table to a comfortable 17 points after second-place Rangers were docked 10 points midweek for entering administration.
Lowly Hibernian remains tied with Dunfermline for last place in Scotland's top tier with 19 points as it has failed to pick up a win in its last four outings.
Celtic dictated play from the opening whistle and grabbed two first-half goals for their efforts. Anthony Stokes struck in the 14th minute before Gary Hooper doubled the lead six minutes later.
The visitors found themselves playing with a four-goal advantage just seven minutes after the restart as Charlie Mulgrew scored in the 47th minute and Hooper added his second goal of the game in the 52nd minute.
Hooper, with 15 goals this term, is two tallies behind former Rangers striker Nikica Jelavic for the scoring lead. Jelavic made the move to Everton in the January transfer window, leaving the door open for Hooper to claim the top spot.
Ki Sung-Yeung put the icing on the cake at Easter Road on Sunday, scoring his sixth goal of the season and Celtic's fifth of the match.
