Badgers in garden help!!!!?

Hi all. Tricky one here. We have a Badger set at the top of our garden. They are welcome to stay even though they do dig the garden up and remove the flowers from their pots. I have just been up the garden to the patio area and noticed that the low brick wall has got large pieces missing! In some areas it has parts that look as something has grazed accross the top. But! one of the bricks (house brick) has a large corner piece missing which is about 20% of the brick. Could this be the Badger! Or do you know were i can find out what the hell has caused this.
