The first thing you should do is talk with him about it. But don't put too much pressure on him. The way it sounds, he might be suffering from cleptomania. Though I'm not a doctor, so don't consider this a diagnosis. Just make sure to tell him that you're not angry at him and itstead are trying to help. If you go too hard at him, he might feel humiliated and just get away and never come back.
Also, tell him that your friendship will suffer if he doesn't change. That way, he will at least think about whether your friendship or all that stuff is more worth it. However, cleptomania or not, people who steal have almost always a problem. Might also be too less income, but what do I know. In any case, he has to be willing to get help. You can't force him to. So be sensible, it might take some time. Just when you see that after some time he doesn't make any attempt to change his behaviour, you should quit your friendship. That's the last option I would suppose If you really like him, but sometimes, it's the right thing to do. some people just don't learn.
