Hazmat Incident at Baltimore Courthouse: Suspicious Powder Found in Envelope

A portion of the Cummings Courthouse in downtown Baltimore was closed and placed on lockdown after a court employee opened a letter addressed from a prison inmate, which contained an unknown white powder substance. Hazmat crews were called to the scene to identify the substance, and three individuals who were potentially exposed were isolated and taken to a medical facility as a precaution. The State of Maryland Health Department later announced that no biological toxins were detected in the powder. The investigation is ongoing to determine the nature of the substance and identify the person responsible.
