MINNEAPOLIS (WCCO) — Crews were investigating what may have caused a suspicious odor to permeate part of the University of Minnesota campus Thursday.
A cleaning crew on campus smelled the odor at about 9 p.m. on the third floor of the VFW Cancer Research Center on the corner of Harvard and Delaware.
Fire crews tested the smell, and it came back negative for anything potentially dangerous.
Crews reasoned the odor may have been coming through the vents from outside and eventually located a scent emanating from a nearby sewer.
Sewer crews were taking samples, and noted readings of some type of chemical in the sewer. Authorities said it doesn’t appear, though, that anyone is in any danger.
The scene was blocked off for a number of hours overnight, but reopened early Friday morning.
