Police in Glasgow have launched an investigation after football thugs clashed outside Hampden early this morning.
The shocking scenes unfolded shortly after 9am as the Old Firm prepared to meet for the League Cup final at the national stadium this afternoon.
Scores of yobs dressed in black, many wearing balaclavas faced off as shocked residents in nearby homes looked on as scuffles broke out and they chased each other, tossing objects as they went.
