Conor McGregor has made headlines after storming the octagon and shoving a referee in an MMA bout he was only watching as a spectator.

McGregor, the two-weight world UFC champion, was watching his team-mate Charlie Ward compete at Bellator 187 in Dublin.

When Ward beat John Richmond on Friday night, an exuberant McGregor entered the arena to celebrate with his colleague.

But McGregor then turned his attentions to referee Marc Goddard, who tried to order him from the octagon.

Another video showed McGregor involved in another altercation as he tried to mount the cage.
