Hi Naveen,
You can do this using the Voronoi Fracture tool, which you will find under the MoGraph drop-down icon, as in the screenshot below. I have added that to the attached file. It still requires additional work from you, otherwise, I will try to return to that when I have the opportunity. You can modify the values in Voronoi to get the desired effect, you can find many tutorials about this tool on YouTube.
I hope this helps you
