Someone's been a very, very, very bold boy.

By someone, we mean Finn - a dog in Ontario, Canada who was 'arrested' by police for attacking a deer after escaping from his house.

His owner, Emme Thompson, snapped a photo of the dog in the back seat of a police car and posted it to Twitter, where it has since gone viral and already spawned countless memes.

Attacking wildlife: not funny at all. Photo of a helpless looking dog in the back of a police car? Hilarious.
