The Washington Suburban Sanitary Commission said Wednesday that the FBI and IRS have seized documents from its main headquarters in Laurel as part of an ongoing investigation.
Amy Thoreson is a spokeswoman for the FBI's Baltimore field office. Thoreson said agents were at the offices for hours on Tuesday, though she declined to say what the investigation was about.
The Suburban Sanitary Commission is a water and wastewater utility serving 1.8 million residents in Montgomery and Prince George's counties in Maryland.
Water commission spokesman Jim Neustadt said in a statement that the commission's police department was aware of the investigation and cooperated with the search warrant, but he also would not provide details. He said the commission turned over all paper and electronic documents that were requested of it and had no reason to believe that it is a target of the investigation.
