Miami police are being investigated for abusive tactics and questionable arrest motives that were caught on a video Halloween night.

The Youtube video shows a group of Miami cops subduing a couple of young men for unknown reasons in Coconut Grove, which is a popular nightspot on Halloween night.

It also shows at least one officer repeatedly punching the suspect at :23 into the video.

The video also shows police grabbing people from the gathering crowd, seemingly at random, and arresting them.
