CELTIC chief executive Peter Lawwell has apologised to Dundee FC after trouble in the away end marred the Boxing Day match at Dens Park.

Following the Parkhead side's 2-0 victory in the Clydesdale Bank Premier League, Tayside Police spoke of a "level of disturbance primarily within the Celtic section of the stadium".

They also confirmed that five supporters, one fan of the home side and four following Celtic, will be reported to the procurator fiscal for "alleged football-related offences".

Mr Lawwell said: "We are very proud that Celtic supporters enjoy such a great reputation and it is therefore extremely disappointing that the behaviour of a small minority has tarnished the good name of the club and our fans in this way.

"Clearly, we apologise to Dundee Football Club - we will work with them and look into any incident which is raised and if we can identify any individuals involved, we will obviously take the strongest possible action."
