What did the window breakers steal? Normally it is done to remove Radio/CD player and speakers, I see in the pic that that both things are still intact (Alhamdolillah). Perhaps security alarm might have alerted the guard of the street if there is any.
I have noticed that these things are done by young boys between 7-12 years of age, esp. those kids who have big bags in which they collect plastic bottles and paper stuff from garbage and those on the road sides. So don't ever let them come to your area.
BTW, it can be done with any car, Liana is not just alone. Seen such incidents happen with Khyber, Alto, Corolla, Premio (side mirrors esp.) etc.
