Two schools were evacuated Wednesday after a gunman claiming to have a bomb opened fire and took hostages at a high school near Bailey, Colorado, officials said.
One hostage, a young girl, was released, but the gunman was still holding four others Wednesday afternoon, said Lance Clem, spokesman for the Colorado Public Safety Department. The Colorado State Patrol is assisting, Clem said.
Several shots were fired at the school, and the gunman is inside, said Jefferson County Sheriff's spokeswoman Jackie Kelley.
She had no information on injuries, but said a bomb squad and SWAT team had been dispatched to the scene.
The Park County Sheriff's office would not provide further details, but said it is dealing with a hostage situation.
The 450 students at Platte Canyon High School and the 340 youngsters at the adjacent Fitzsimmons Middle School were evacuated, officials said.
The students were evacuated to a safe place about 12:10 p.m. (2:10 p.m. ET), the Park County School District superintendent's office said
