A police report has shed new light on an alleged racist incident at a Chicago-area Buffalo Wild Wings last month in which a group of black customers said they were asked to change tables because of the color of their skin.

A report released late Wednesday by the Naperville Police Department reveals the central figure of the episode is a man with a Swastika tattoo, a regular known for making racist comments and sending back food orders not served by white employees.

According to the report, the man and a female acquaintance frequented the restaurant during the last few years to watch their favorite sporting events on TV.

Their names, along with the names of the complainants, were redacted and not identified by police in the report.

The incident happened Oct. 26 when a group of 18 customers, most of whom were African American, visited the restaurant for a child’s birthday party. After being seated, the group told police, employees asked them to move to another table because a white customer sitting nearby didn’t want to sit next to black people.

The white couple had been sitting at their table for about two hours when the hostess seated the group of 18 directly behind them, the police report said.

The man and woman told investigators they never said anything to the group nor did they ask for the group to be moved from their table. The man's female acquaintance, however, told police she pulled their table a few inches away from the group only to create more room for the servers to move between tables.

The man also told police that Buffalo Wild Wings employees “had heard him make racist jokes and comments in the past” about black people, the report read. As a result, staff members “took it upon themselves" to ask the group to change tables.

Chief Robert Marshall said his department investigated the incident because the restaurant received several threatening phone calls afterward, including one from a person who threatened to burn down the business.

Attorney Cannon Lambert, who represents the black customers, said in a news conference last week that a lawsuit could be avoided if Buffalo Wild Wings changes its policies on hiring and training employees.
