Plot to kill Barack Obama uncovered

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.
