Guru Ki Golak looted and they know who did it

It was a surprise when I saw this news in a southern newpaper but I did not notice this report in Tribune. It seems 2.75 Lakh was stolen from the treasury of the Golden Temple, but no Police case has been filed. Those in charge of securing the room are no suspected of this act, but SGPC is not handing the case to Police to find the culprits. Does SGPC have its own detectives? How does SGPC plan to catch these people without Police help?
