Re: Larceny: Macbook Not Mine
what you shouldn't have done was take it home. Even if there was no intent to steal, it looks like there was. Since you took possession of the computer, you put yourself in the position of having to deal with the thing. Since you asked around, the next step would be to contact the police, even if you did it via telephone, and ask them what to do with it.
Now, as the other poster stated; turn it into the police
