Traditionally, it's china shops that fear a mighty bull entering the premises.
But one bull entered a different kind of establishment during the annual bull run at a festival in Cheste, Valencia, Spain.
The half tonne beast took a break from chasing revellers to slip inside the door of a Bankia branch.

Several runners followed the bull into the building and held the door open so it could emerge onto the street and continue on its way.
