Who Makes DUI Arrests in Lake Forest Park
The King County Sheriff's Office and the agency that reports for Lake Forest Park (filed by the FBI as Lake Forest Park Police Department) make the DUI arrests in and around Lake Forest Park.
The FBI's agency list also places these agencies in King County: the University of Washington (campus police); the Port of Seattle (other agency).
Together, the 36 agencies in King County with all twelve months of 2025 on file reported 31,397 arrests to the FBI that year, all offenses together; the FBI's count for King County does not break DUI out.
