Mysterious ‘HELP’ and ‘TRÁFFICO’ signs that are visible on Google Earth are causing concern in downtown Los Angeles. Satellite imagery shows the lettering constructed from old pipes and wood chunks near rows of shipping containers.

Located at the intersection of Cesar Chavez Avenue and Mission Road, the messages were spelled out in apparent construction debris and read “Help,” “LAPD,” and “Trafico.” There are also signs that appear to spell out “Federal,” “FBI,” and something related to terrorism.
