Four men have been charged in last month's robbery of Miami Heat forward Antoine Walker at his Chicago town house, authorities announced Friday.

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

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

The robbery occurred July 9. Walker, a Chicago native, was at the home with a relative when multiple 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 occurred 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.

Chicago police have said they're trying to determine if there are any links between the cases.

Police were expected to release more details about the charges against the men accused in the Walker robbery at an afternoon news conference.
