Police have arrested one of the people suspected of threatening violence against Urbana High School.
The arrest of a 16-year-old girl took place on Tuesday in Chicago.
Urbana Police say the teenager is one of the people who threatened on Nov. 7 to bomb and shoot students at the high school. The Urbana school district responded by canceling school that day and sending students already on buses back home.
Since then, the district has received other threats of violence and responded with lockdowns and remote school. Police say they are treating the threats two weeks ago as separate from the threats last week.
Police also say they believe this to be part of a national trend and that those at the school were not in imminent danger.
Urbana Police worked with the FBI and Chicago Police to investigate the case.
