You might just let go the pinch to avoid the hassle of calling the police. However IMO, in addition to the possibility of getting your stuffs back, reporting the incident to police should prevent such incidents from happening in the future, at least, in the same compound for others benefit. It will also send a caution signal to the residents and could help the culprit being singled out.
People bearing with such occurrences is the main reason why these incidents are on the rise in Qatar lately, I thought.
