The teacher is accused of placing the tape on the mouths of ten students; three other students taped their own mouths, said district leaders. They were all sent to a school nurse for observation, then sent back to class. The teacher was immediately removed and banned from the campus, a school district leader said. "Everyone of them checked out. They're all fine, but it could've been a dangerous situation, no question. And that's the type of thing that can make a child sick or cause other problems,"
