Video shows armed gang at troubled Colorado apartment building believed to have been taken over by migrants

Potential gang activity was caught on surveillance camera in a Colorado apartment building after what one former resident calls "no accountability" kept law enforcement from assisting.

The video shows many men armed with handguns, and one with a scoped rifle, bursting through the door of the apartment complex for unknown reasons.

The group appears to be Tren de Aragua, or TdA, a transnational gang based out of Venezuela. The gang, with reportedly 5,000 members, has a motto of "real until death," or "real hasta la muerte."
