COUNCIL BLUFFS, Iowa (AP) — The Council Bluffs Community School District says a 14-year-old boy has been charged with first-degree arson in connection to a high school fire.

District officials said Wednesday that two boys were involved in the Tuesday incident at Abraham Lincoln High School. They say authorities interviewed a 15-year-old boy but he hasn’t been charged.

No injuries were reported after sprinklers extinguished a football tackling dummy in the school field house. Students were evacuated for about 10 minutes while firefighters helped vent smoke.

Fire officials haven’t released the suspects’ identities.
