It was a mystery smell which caused a lot of concern in Ventura Thursday.
People reported a gas-like smell in the Pierpont area of the city at around 11:30 a.m. Thursday. Dozens of first responders spread out through the community.
As a precaution, several homes were evacuated, as was Pierpont School. Urban search and rescue teams used ventilation systems to lower the gas levels in a sewage line.
All evacuation orders were lifted by around 6 p.m. Exactly what led to the issue is still under investigation.
