A fight has gone viral over the weekend in Alabama over a disagreement at a dock. The city’s mayor issued a statement on Sunday that said, in part, “The Montgomery Police Department acted swiftly to detain several reckless individuals for attacking a man who was doing his job.”

The video shows a security guard talking to the group, before they began attacking him.

Montgomery police said there are now arrest warrants out for four people, and more could come after police review more video footage.
