Police forces dance: Who won the detective dance-off?

The police in Scotland have joined the New Zealand Police and the NYPD in the "running man" internet craze - with their videos attracting millions of hits.

The Kiwis were first to take part in the #runningmanchallenge with their social media post, and invited 10 other forces to get involved.

The social media meme involves people filming themselves dancing to the 1990s hit My Boo by the Ghost Town DJs, posting the video and challenging others to do the same.
