Like snorko, all I had to do was provide a form and a copy of the police report and I got a check too.
Interesting thing about police reports ... shows all the detective's notes and stuff too. Needless to say I'm pretty peeved at the CSPD (and the detective in particular) who seemed more interested in investigating ME for "filing a false report" of the theft then in actually catching the thief (I think the detective was more interested in impressing one of the female suspects than doing his job).
I recommend that whenever you use the services of the police, you get a copy of the report.
