Authorities say they thwarted a plot to murder and castrate Justin Bieber and his body guard. Two men from New Mexico had allegedly discussed their plans to gruesomely murder the pop star when he visited Madison Square Garden for a recent concert. Dana Martin, a man serving two life sentences for the rape and murder of a 15-year-old girl, supposedly ordered the hit after befriending one of the would-be assassins when they served time together. Martin—who has a tattoo of Bieber on his leg—was also the person who gave authorities the heads up about the murder plot. When police arrested one of the would-be killers in New York, they found weapons and pruning shears on him. [The Hollywood Reporter]
