Four people have been arrested in Denver for allegedly plotting to kill Democratic presidential candidate Barack Obama.
One man was arrested on Sunday after police found two high-powered rifles in a rented pick-up truck he was driving. Another man arrested was reported to be wearing a swastika and was thought to have links to white supremacist groups.
Denver-based TV channel CBS34 said one of the men arrested had told authorities that they were going to shoot Obama from a high vantage point using a rifle.
The shooting was planned for 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.
