Las Vegas ? Former NBA star Charles Barkley has retired his debt to a Las Vegas Strip casino that sued him after he failed to pay $400,000 in gambling loans.

But the civil lawsuit remains open, and it’s going to cost Sir Charles $40,000 more to get out of the legal doghouse.

Barkley, a basketball analyst for Turner Network Television, said in a statement released Tuesday by TNT that he didn’t know about the district attorney’s $40,000 processing fee, but intends to pay it.

“True to my word, I sent a $400,000 cashier’s check overnight to Wynn Las Vegas, which they confirmed they received,” Barkley said. “I was unaware of the additional 10 percent processing fee from the district attorney’s office and will make restitution on that promptly.”

Jennifer Dunne, a spokeswoman for Wynn Las Vegas, said it received a check Tuesday afternoon from Barkley and sent it to the district attorney.
