Nothing hazardous was found but the pilot was taken into custody awaiting charges.

Earlier in the day a local newspaper reported that pilot Doug Hughes (61) planned to make the flight to draw attention to the issue of election campaign finance reform.

The security scare comes after a man shot himself dead in front of the Capitol on Saturday sparking a temporary lockdown.
