Police - including horse-mounted units and multiple vans - are seen attempting to control the fracas in Glasgow's east end.

Objects can also be seen being launched from one set of fans to the other across the road outside the stadium.

Now four men, including a teenager, have been arrested as a result of the violence with one charged with allegedly assaulting two police horses. 

A police spokesperson said: "Officers continue to investigate a number of incidents of disorder from a small element of both home and away supporters at the Celtic V Airdrionians match at Celtic Park on Saturday 19 January 2019.

"Officers will be reviewing online images and CCTV as part of this investigation."

The four men are due to appear in Glasgow Sheriff Court.
