Federal investigators executed a search warrant Wednesday at an aerospace manufacturing facility in Southern California, where a chemical tank malfunction last month led to the mass evacuation of 50,000 area residents.
The FBI action comes after the overheating of a chemical tank at the facility raised serious safety concerns, with officials worried the situation could lead to an explosion that would endanger the surrounding community.
The large-scale evacuation affected tens of thousands of people in the vicinity of the aerospace plant as emergency responders worked to address the potentially dangerous chemical emergency.
