MACOMB COUNTY, Mich. -- Two Macomb County teens may face felony charges after one teen built a homemade stun gun and the other brought it to school.

Macomb County Sheriff Mark Hackel said a 13-year-old boy found instructions on how to make a stun gun out of a disposable camera and some hardwires off the Internet.

The boy gave the gun to his 18-year-old friend who brought it to Dakota High School and showed his friends.

Watch: Student Brings Stun Gun To School

"He didn't think it was much more than a gag, but what he didn't realize is he could be charged with a felony," said Hackel.

Investigators said the school called the Sheriff's Department after they learned the student was using the homemade stun gun to shock students.

Nobody was seriously injured.

Macomb County parent Larry Beard is disappointed that students can find such dangerous recipes online.

"What are they going to come up with next," said Beard. "You are fighting tooth and nail against this thing but it's a lot bigger than any of us."

The school district said it is deciding whether or not the students will be suspended.

Meanwhile, the sheriff's department has turned the case over to the prosecutor's office, which will decide if the student's will face felony charges.
