Earlier today, Siohvaughn Wade had blown off a court hearing in Chicago regarding her ongoing divorce war with the Miami Heat star -- so the judge threatened to issue a body attachment order unless she showed up in the afternoon.
The deadline came and went -- and Siohvaughn never showed.
Now, the judge has issued the order -- which means cops will now seek her out, take her into custody ... and deliver her to the judge.
As we previously reported, Siohvaughn has made several sensational claims about Dwyane -- most recently accusing the NBA star of engaging in "sexual foreplay" with his new girlfriend in front of his kids.
Dwyane -- who was present at court today -- has denied all of Siohvaughn's allegations.
