LORAIN, Ohio -- Police departments use the x26 Taser to shock unruly suspects into submission, but Lorain residents are stunned that an officer used one on a school bus to subdue to 12-year-old boy, reported NewsChannel5.

According to the police report, police were called to remove the boy from the bus after he tried to steal another boy's CD case.

Police Capt. Russ Cambarare said the boy cussed at the officers and then threatened her.

"Then he made a threat that he was going to kill her, he bucked his head backwards and hit her on the chin and broke one of his arms free," said Cambarare.

Outside, at the corner of East 30th and Vine, what police are calling an angry mob was pounding on the bus, demanding the officer let the boy go.

Still, some residents are saying police shouldn't use a Taser on a child.

Cambarare will determine if the use of force was within policy. The officer involved is still on the job.

The school district's also investigating, and when classes resume in the fall, the boy could face suspension or expulsion.

Police have charged with boy with robbery, assault on a police officer and resisting arrest.

They say neither the boy or the officer were hurt in the scuffle.
