Police in the US say they have foiled a plot by two students to go on a killing spree in their school today.
The 15-year-olds planned to rob gun shops in Sacramento, California, and murder fellow students in a repeat of the 1999 Columbine High School massacre.
It is thought they had targeted black pupils and would also use explosives.
Officers were able to thwart the attack - planned for lunchtime today - after a tip-off from a student who overheard the plot.
The unnamed duo, from Laguna Creek High School in Elk Grove, California, were arrested on suspicion of conspiracy, making terrorist threats and hate crime charges.
Their homes were searched and a .22-calibre rifle owned by one of their parents was impounded.
Officers also found Nazi-style drawings and a map of the school cafeteria.
One of the students was arrested on Monday and the second on Tuesday. Four other students were questioned in connection with the plot but were not arrested.
