One Walker building described as slum

CHICAGO -- Former NBA All-Star Antoine Walker is apologizing for "unacceptable" living conditions at Chicago buildings owned by his companies.

Walker told the Chicago Tribune he wants to "humbly apologize" to everyone who's been affected by the failings of his companies, Walker Ventures LLC and AW Realty LLC.

One building has been described as a slum nuisance by the city. A broken sewer pipe filled the basement with feces and debris, and bricks tumbled from the building's facade.

Over a dozen lawsuits have been filed against Walker's companies over poor management and unpaid debts.

Walker is also facing criminal charges over gambling debts to three Las Vegas casinos.

Walker played for Boston, Dallas, Atlanta, Miami and Minnesota during his 12-year career.
