Nearly a dozen people, including a firefighter and police officer, were evaluated at a hospital after being exposed to an unknown gas in Riverside that had prompted the closure of a local school and evacuations in the area.
The Riverside Fire Department tweeted that people were being evacuated from 10th Street to 14th Street and Victoria Avenue to Howard Avenue around 8:04 a.m. because an unknown gas substance was leaking.
A firefighter and police officer were evaluated at a local hospital for possible exposure to the gas during early stages of the investigation, the department tweeted.
At least nine others were also hospitalized, the Los Angeles Times reported.
"The Isolation Zone" was later expanded one block west of Howard Avenue to Commerce Street, the department tweeted at 8:57 a.m.
"Please note that the gas leak is not on our campus, but at a residence behind the campus. However, as a safety precaution we have closed school for the day. Hazardous materials teams are in the area assessing the situation," the school district website stated.
