CHINO, Calif. (KABC) -- A teen who had been arrested for allegedly making online threats of a "Columbine" shooting at Chino High School has been released after police determined the threats were made by a different individual, officials said Wednesday night.
Officers arrested a 15-year-old student who attends the school on Wednesday and say he confessed to posting the threatening messages and had acted alone. They say no weapons were found at his Ontario home.
They released the initial suspect who had been arrested Tuesday, identified as a former student who had been expelled by the school previously for unrelated reasons.

The online threats included tweets such as "I'm recreating Columbine" and "Chino needs a good shooting," according to a group known as "The Tactical Institute," who spotted the tweets and reached out to law enforcement.
