TAMPA, Fla. -- Two students are facing charges after allegedly making threats against their schools.

The students, who were not named in a Tampa Police Department news release, were arrested Monday and Tuesday.

Police say the threats were not credible in each case.

A 15-year-old student, despite being suspended from Middleton High School, was on campus Monday, according to police. They say when he was asked to leave, he responded by saying: "I'm going to come back tomorrow and shoot this b** up. I don't give a f** ..."

His mother was called to the school and cooperated with officials. Police determined he did not have any firearms.

The second student had a disagreement with his teacher about his grade at Robinson High School and reportedly told that teacher, "If you do not change my grade, I will shoot up the school." The 16-year-old teen was arrested Tuesday and still, while he did not have any firearms, was also charged.

Both were charged with making a false report concerning the use of a firearm in a violent manner, a second-degree felony.

School and police officials want to make clear, "if you see something, say something," especially given shooting in Parkland, Florida, that left 17 people dead. Hillsborough County Schools superintendent Jeff Eakins and Tampa Police chief Brian Dugan urged parents to have conversations with their children.
