According to The Irish Independent, via Bloody Elbow, McGregor is under investigation by local police.

"We are investigating the circumstances under which the photo was taken. Gardai from Crumlin are investigating," a Gardai spokesperson said.

McGregor has since apologized in another Instagram post.

5. Media instigators/An Garda Siochana. I apologise for having the air-soft in public. I was simply rehearsing for a potential upcoming film role. I understand that the more traffic a story can get the more revenue it generates. So I understand and respect that the media must create these stories and these situations even if at times it is at other people's expense. We've all got to eat. And I eat well. So I will not complain.

The featherweight champ is rumored to battle dos Anjos at 155 for the lightweight crown at UFC 197.
