The warrant is for a traffic violation and she was not properly discharged.
A warrant is a warrant. She is subject to arrest when found. Was it prudent or necessary, that is another story. If it is traffic there is bail on the warrant. Post the bail and off to home she goes. You get the bail back is she goe to court when requested. Make sure they have her correct address..
If there is a warrant for her arrest, the police can arrest her whenever they find her. Post bail to get her out. Then hire an experienced traffic ticket attorney.
I am surprised they did not call the judge and ask that the warrant be withdrawn. But if the police are ordered to arrest, they have no choice.
