Wait until they are asleep, steal their stuff and then leave. Or choose to not back them up during a fight, start some rumors at the local bar, you can do all kinds of things to mess them up and........ oh wait you are asking how to resolve this.
Honestly since this has happened before with other characters, it sounds more like one person is just picking on the other person and using their characters to do so.
Talk to your players, especially the one who is doing the stealing, find out why he is doing this. If it is causing a problem with the players, tell him.
Without being there though, I have a hard time giving any better advice than this.
