Attorneys representing the city of Baltimore are asking a federal judge to prevent some of the crew members from the cargo ship that crashed into the Francis Scott Key Bridge from leaving the country.

In a Tuesday court filing, the attorneys claimed that they were informed earlier that day that some of the Dali crew members would be leaving the country as soon as Thursday. The crew has been on the vessel since the bridge collapsed in March. The city’s attorneys requested an emergency conference, acknowledging that the court would be closed Wednesday due to the Juneteenth federal holiday, to attempt to keep the crew from leaving the country as investigations continue.
