Four held in 'plot' to kill Barack Obama

DENVER, Colorado, (AFP) - Four people have been arrested in Denver amid fears of a plot to kill Democratic White House hopeful Barack Obama, a local report said Monday.

Denver-based CBS34 said one of the men arrested had told authorities they were “going to shoot Obama from a high vantage point using ... a rifle ... sighted at 750 yards (meters).”

The shooting was supposed to happen on Thursday when Obama will accept the nomination as the Democratic Party’s presidential candidate for the November elections at the 75,000-seat Invesco stadium, the television station reported.
