Northern Territory Police, Fire and Emergency Services have joined the 'running man' dance club - releasing a video on their Facebook page which features two crocodiles and segways.

"The Northern Territory Police, Fire and Emergency Services thank everyone for their support since our unfortunate omission from the?#?runningmanchallenge," they wrote on Facebook.

"Challenge accepted (and smashed) and extended to Singapore Police Force New Orleans Police Department Polizei Berlin Police Nationale."

The video shows police dancing at Darwin aquarium Crocosaurus Cove Darwin in front of a tank containing a frighteningly large croc.

Two officers are swimming in the tank, inside a protective clear tube.

A solo is performed by one police officer, who shows off some impressive leg-wiggling before removing his belt.

Luckily the video ends before he removes any other items of clothing.

Yesterday the Australian police force released a brooding video Moving Pictures song What About Me.

Their hurt was also palpable in a message accompanying the video: "Hey NZ Police Recruitment did you forget us when challenging every jurisdiction in Australia (and the world) to the #runningmanchallenge? #whataboutus #NTpolice."
