Georgia Department of Revenue agents raided all three of Knight's chicken restaurants in the state on Tuesday (21Jun16) and confiscated computers, files, and the contents from safes.

According to TMZ.com, Gladys' son Shanga Hankerson, who runs the locations, is being investigated following reports he inappropriately diverted $1 million (GBP680,000) in funds. Knight is reportedly not being investigated.

It is unclear when the restaurants will re-open.
