Washington: Three people, including two juveniles, have been arrested in connection with an alleged plot to carry out a shooting at a high school in metro Atlanta, authorities said Tuesday.

The announcement of the alleged plot comes after a 16-year-old boy killed three children and a teacher in a shooting at Silver Rail Elementary School in central Oregon.

The FBI discovered threatening posts online from one of the trio and worked with local police to make the arrests on Oct. 20 and Oct. 23, apprehending two of them in Georgia and a third in California, the Canton Police Department said in a news release. They found weapons and ammunition.

They were arrested on suspicion of conspiracy to commit murder. Police said one of the suspects is 21 years old and another 17, but they didn't provide the age of the third suspect other than saying he is a juvenile.
