Supervisory Deputy U.S. Marshal Robert Clark told the Inquirer that it is unclear whether the vandalism was a targeted act. Investigators are looking into potential links to similar crimes in Old City on Monday.
The courthouse is home to the U.S. District Court for the Eastern District of Pennsylvania and the U.S. Court of Appeals for the Third Circuit.
The U.S. Marshals Service, Federal Protective Service and Philadelphia Police Department did not immediately respond to a request for comment.
