Gladys Knight’s Chicken & Waffles—an Atlanta restaurant chain owned by the Grammy Award-winning soul singer—was raided by agents from the Georgia Department of Revenue, WSB-TV reported Tuesday.

According to TMZ, who later picked up the report, authorities seized files, computers, and “the contents from safes” from three locations in relation to an investigation of Knight’s son, Shanga Hankerson, who runs the business.

While WSB-TV reports that Knight herself is not under investigation, her restaurants have been temporarily closed and authorities believe $1 million may have been “inappropriately diverted.”

“I was made aware of the tax situation,” James Boyd, who claims to be a consultant for the chain, told WSB-TV. “It’s our intent to get the business back open. The business will go on. I want the public to know both sides.”

The restaurant was in the news earlier this year after receiving a 56 on a health inspection. At the time, Hankerson told reporters that it was an "ongoing effort" as far health and cleanliness of the restaurant was concerned, and joked that he didn't want to "get a whooping at home.” Knight made an appearance at the restaurant in February to ease customers' concerns. 

"Our biggest thing was a freezer door that was off, but we weren't using the freezer,” she said. “The freezer was dead. They cited us because no door; I get that.”

"[My son] was so upset about this,” she added. “I had to really calm him down."
