Colorado school shooting leaves two students injured, suspect dead

At least two students have been injured in a shooting incident at Arapahoe High School in Centennial, Colorado.

Arapahoe County Sheriff Grayson Robinson said on Friday that the shooter is dead from what authorities believe is a self-inflicted gunshot wound.

The incident forced hundreds of students to run away in terror and many others to huddle in the corners of locked-down classrooms.

The school is part of Littleton Public Schools and has more than 2,000 students. Some schools in the area are in lockdown mode.

Police have not released the identities of the victims.

According to officials, at least one student was critically injured.

Saturday is the one-year anniversary of the Sandy Hook school shooting in Connecticut.
