Students at Cass Technical High School in Detroit were evacuated Tuesday after a gas odor was reported inside the building, sending students out of class with no immediate word on when they would be allowed back in. DTE crews descended on the school to try to pinpoint where the smell was coming from, according to school officials.

The evacuation was reported by CBS News Detroit, which said DTE crews were investigating the origin of the gas odor. Cass Tech sits on Second Avenue near Grand River Avenue and the Fisher Freeway/Interstate 75.

No Timeline Yet For Dismissal Or Return

As of Tuesday, school officials had not determined when students would be dismissed or whether classes would resume in the building that day, per the same CBS Detroit report. Families were expected to receive a letter addressing dismissal plans, though the station's report did not specify exactly when that notice would go out or what it would say about reopening.

Cass Technical High School enrolls more than 2,400 students in grades 9 through 12 and is part of the Detroit Public Schools Community District.

What To Do If You Smell Gas

DTE Energy's safety guidance instructs anyone who suspects a gas leak to leave the area immediately and call 911 from a safe location rather than investigating further or trying to locate the source themselves. That guidance, outlined on DTE Energy's emergency safety page, underscores the importance of leaving the area and calling 911 from a safe location.

It remains unclear what caused Tuesday's odor or whether DTE crews have located its source, and officials have not confirmed any results of testing inside the building. Hoodline will update this story as school officials release more information about dismissal times and whether students will return to Cass Tech on Tuesday.
