DENVER — As classes resume at Arapahoe High School, state officials are reminding students about a hotline to report threats.

Attorney General John Suthers and state lawmakers are promoting the Safe2Tell hotline Tuesday. It's an anonymous threat-gathering system created in 2004 for students and teachers to report threats and bullying.

State officials say the hotline has prevented more than two dozen school attacks since its creation.

The hotline was a recommendation of the Columbine Commission, a state panel that reviewed school safety after the 1999 shootings at Columbine High School.
