Police and witnesses said two offenders held Walker and at least one other person at gunpoint during the robbery, Chicago broadcasters reported from the scene in the city's River North neighborhood last night.

Walker's agent, Mark Bartelstein, confirmed the incident took place but said he could not give specific details.

"He's OK," Bartelstein told The Associated Press. "There was a robbery. It's a scary thing. It's a terrible thing. He's trying to get himself back together. Police are there and he's getting it taken care of."

Chicago Police spokesman Hector Alfaro said officers responded to a robbery at a home in the neighborhood about 7:30 p.m. EDT, but could not confirm that the home belonged to Walker. A vehicle, cash and jewelry were reported stolen and there were no injuries, Alfaro said.

Bartelstein said Walker was with a relative at the time of the incident.

Walker was not available for comment. The Heat were aware of the incident, a team official said, but had no other comment while they attempted to gather facts.

In July 2000, Walker — then a Boston Celtic — was the victim of an armed robbery along with NBA center Nazr Mohammed as they sat in a vehicle waiting for a restaurant on Chicago's South Side to open. Police said at the time that three men approached and demanded cash and valuables, which included a $55,000 wristwatch.

Walker, a three-time All-Star, averaged 8.5 points with Miami this past season and was a key part of the Heat's run to the 2006 NBA championship.
