The four are charged with home invasion, armed robbery and aggravated kidnapping, Cook County state's attorney spokeswoman Tandra Simonton said Friday.

She identified the suspects as Phillip Allison, 28; Antoine Larkins, 28; Demorris Hill, 25; and Gregory Reedfield, 23.

Walker, a Chicago native, was home with a relative July 9 when masked robbers bound the two with duct tape and held them at gunpoint. They made off with Walker's Mercedes, cash and jewelry.

The robbery happened less than three weeks before New York Knicks forward Eddy Curry, his wife and an employee were also tied up and robbed by masked gunmen at Curry's home in suburban Chicago.
