On March 10, 10 people complained of being sickened in an underground parking structure in Westwood, but none of them required hospitalization.
The incident was reported at 7:11 p.m. in the 1000 block of Glendon Avenue, just south of the UCLA campus, according to Sean Saunders of the Los Angeles Fire Department.
The patients complained of a burning sensation, a metallic taste in their throats and feeling sickened, Saunders said.
No one was taken to a hospital, but a hazardous materials crew was dispatched to take samples and try to determine what substance was involved.
