Police Scotland is investigating after Rangers fans allegedly threw glass bottles at Dundee United supporters on Saturday.

As the Glasgow Times reported at the time, away fans at Ibrox interrupted the minute's silence in honour of The Queen.

Boos and chants of "Lizzie's in a box" were heard, as the rest of Ibrox fell silent to pay their respects.

A Police Scotland spokesperson said: "An investigation has been launched and further enquiries are under way."
