Police said a restaurant manager was burned in a scuffle after an angry customer ordered two young men to attack him.
The Madison Police Department said a customer was trying to get a refund at the Park Street McDonald's Wednesday at 4:43 p.m. using a receipt from another restaurant.
The woman became belligerent, berated the 27-year-old manager and ordered her "sons" to come in from the car and attack the man, police said.
Two young men came in from outside, hopped the counter and knocked the manager to the floor, punched him and tried to hit him with a pot full of coffee, according to the report. The pot broke and splattered hot coffee onto the victim's arm, burning him.
The woman and the two young men -- who police said may or may not be her sons -- fled the McDonald's in a green, late 1990s-model Pontiac Bonneville with Illinois plates, police said.
One of the young men also grabbed a handful of cash from an open cash register as he ran out, according to the report.
Police shared two surveillance images Thursday showing the attackers and the woman.
One of the men was described as black, in his late teens to early 20s, and wore a gray hooded sweatshirt and red plaid pajama pants, according to the report.
The other man was described as black, in his late teens to early 20s and wore a black jacket and jeans.
The woman was black, with a heavy build, between 40 to 50 years old with long black curly hair, the report said. She wore a long tan or gold coat with a fur collar and black-framed glasses.
Police asked anyone with information to call Madison Area Crime Stoppers at 608-266-6014.
