BOULDER, Colo. (AP) -- Two University of Colorado students accused of providing marijuana-laced brownies to unsuspecting classmates and a professor have been arrested and face several felony charges.

The Daily Camera reports (http://bit.ly/UObHbd ) 21-year-old Thomas Ricardo Cunningham and 19-year-old Mary Elizabeth Essa were arrested Saturday on suspicion of second-degree assault and inducing the consumption of controlled substances by fraudulent means, along with two conspiracy counts.

CU Police spokesman Ryan Huff says officers were called Friday morning after a history professor complained of dizziness and losing consciousness. The professor, who was not identified, was hospitalized. Two students in the class who ate the brownies also were hospitalized and five others were sickened.

Police say Cunningham and Essa baked the brownies and brought them to class as part of a "bring food day."
