Authorities, including the FBI, SWAT, and Hazmat teams, have conducted a series of raids on homes in Las Vegas following the discovery of a possible illegal biological lab. The probe has expanded significantly, as over 1,000 items have been sent for testing amid concerns about connections to a similar operation in California. A home in northeast Las Vegas is at the center of this investigation, with links suggesting ties to a Chinese-operated lab in Reedley, California. Multiple arrests have been made, including a property manager, while local residents express unease over the findings. This situation has sparked calls for legislative hearings on public health regulations related to biological labs.
