DURANGO, Colo. (CBS4)- Classes resumed Friday at Durango High School after a prank kept students off school grounds since Monday.
The prank involved bales of hay that caused air quality issues.
Students in the senior class are suspected of scattering more than 30 bales of hay throughout the halls of Durango High.
School officials said they want whoever is responsible for the hay to come forward. The cost of the cleanup is expected to be more than $100,000.
