A shocking video shows a crew of gun-wielding men storm through a Colorado apartment building overrun by the violent Venezuelan prison gang Tren de Aragua, which has overtaken multiple housing complexes in the area.

In the clip, obtained by Fox Denver, a group of heavily armed men — including three with handguns and one with a rifle — can be seen in surveillance video entering another troubled apartment complex in the Denver suburb of Aurora and breaking into a unit.

The Aurora Police Department acknowledged it is “aware that components of [Tren de Aragua] are operating in Aurora,” saying that the police force “has been increasingly collecting evidence to show the gang is connected to crimes in the area.
