That's his wife, so, I doubt he was being arrested. If you compare an image of Blunt's wife and the video, you'll realize it's definately his wife. I have no idea why he is walking like that. It does look very odd, to say the least.
Many people saying thats NOT his wife. Who to believe? Hmmmm

I've looked at it from many images to compare with. I'm no expert, but It looks exactly like Blunt's wife in the video. I believe it is his wife.
