Informed by whom? An order issued by whom?
Just because your friend doesn't know the reason doesn't mean there isn't a good reason (assuming an order actually exists, which is anything but certain based on what you've told us).
No way to know based on the scant information provided.
You obviously have no way of knowing that, and there are at least a few things more than what you have been told (as indicated by the questions I asked).
At 7:15 p.m. last night, when you made your original post, you wrote, "The only thing that makes sense is that the officer or DA wants to try and flip his wife and get her to testify against him or something." Then, less than an hour later, you substantially narrowed that statement to one that absolutely certain. What happened in the 58 minutes between your posts that caused the change?
