Irvine supermarket staff were left shocked when an employee appeared to be tripped up by a 'ghost'. 

Bourtreehill Supermarket staff member suffered the fall earlier today - which was captured on the shop's CCTV.

But when they looked back at the footage - the crate appeared to move by itself.

Shop boss Imran Ali has since took to social media joking that it was the shop's resident ghost Stacy.

Imran confirmed the staff member was uninjured after the trip, only suffering a 'sore butt'.
