According to the search results, there was police activity at the terminal roadway of BWI-Marshall Airport on October 11, 2023. The roadway was temporarily shut down during the investigation, but flights appeared to be departing and arriving as scheduled throughout the closure. People inside the airport were advised to remain in place, and multiple audio announcements were made in the terminal to update travelers. The Maryland Transportation Authority said Light Rail service for BWI is operating once again following the investigation. One person was taken into custody for making "precautionary statements" to an officer at BWI Thurgood Marshall Airport that forced the terminal roadway to shut down. There was also a bomb threat reported at the airport on the same day, but police cleared the airport after investigating the threat.
