An officer of the French Police once made satellite contact with the Justice League, appearing on their Justice League Monitor in the Hall of Justice. He told them that the Mummy that had escaped from the Metropolis Museum of Natural History had arrived in Paris.
from the Real World
There are actually two police agencies that represent the French government. It was never made clear which one it was that was being shown in the episode. Unfortunately both agencies are headquartered in Paris so that doesn't even provide a clear hint. The insignia that the police officer wore is no hint either, as it doesn't match any real world French Police agency.
