Wisconsin police hunt woman who attacked McDonald's worker over incorrect breakfast sandwich

Police are hunting a US woman who attacked a McDonald’s worker after receiving the wrong breakfast sandwich.

The woman had ordered a bacon breakfast sandwich at a drive-thru in Wisconsin on Sunday but was mistakenly given a sausage sandwich instead.

She suddenly became angry and hit the employee in the back with the bag of food, Glendale police said.

CCTV footage shows the woman then walk into the store and begin shouting at workers, accusing them of not replacing the sandwich with the correct one.

She tried to confront the manager, despite apparently receiving a refund, before a 17-year-old female worker attempted to intervene.

But the woman, wearing a blue shirt, shoved the teenager into the fry station. She subsequently hit her head on the machinery and again on the floor.

She was taken to hospital to be checked over but did not suffer any serious injuries, and was not burned by the fry grease.

Glendale Police launched an appeal to identify the woman following the incident, hoping to pursue assault charges.
