Letters obtained by The Denver Gazette from the law firm representing CBZ Management — whose apartment complex in Aurora was shut down over what the city described as safety issues last month — show officials were fully aware weeks ago of accusations that a Venezuelan gang had “forcibly taken control” of the property.

In an Aug. 28 letter to Colorado Attorney General Phil Weiser, the law firm wrote that CBZ Management had been informed that “Aurora Multi-Family Projects have been forcibly taken control of by gang(s) that have immigrated here from Venezuela.”

Based in Brooklyn, CBZ Management operates rental apartments in New York and Colorado with 11 properties in Denver, Aurora, Colorado Springs and Pueblo.
