Key points:

• Bodycam vision showing the arrests attracted hundreds of comments

The video, which is overlaid with up-tempo rock music, shows officers and a police dog pursuing one of three teenage boys through bushland outside of Darwin after intercepting a vehicle.

The arrests, made on Wednesday afternoon, came after the three 16-year-old boys allegedly stole two vehicles.

The boys were intercepted using tyre deflation devices in Darwin's rural area and charged with multiple property offences.

After being posted to the Facebook page of the Northern Territory's Police Fire and Emergency Services on Thursday evening, the video had received over 1,100 reactions and 220 comments.

The vast majority of comments praised the actions of police.

But several comments — which were removed after the ABC approached NT Police — included remarks such as "hope the dog had a taste" and "let the dogs take a couple of chunks".
