A Michigan prosecutor has filed a terrorism charge against a man accused of stabbing 11 people at a Walmart store.

DETROIT A black woman who was seen on video being punched by a Michigan sheriff's deputy bit the officer before she was struck, the sheriff said Friday. Washtenaw County Sheriff Jerry Clayton played video and audio from the confrontation with ShaTeina Grady El, which occurred Tuesday night while deputies were investigating a shooting in Ypsilanti Township. The body cam doesn't show the deputy striking Grady El because they were so close together, the sheriff said. Hundreds of people have protested at the sheriff's office this week in response to the phone video of Grady El being hit. Grady El has two unrelated cases pending in Wayne County, including a charge of resisting police in Canton Township.
