Cancel Sprint
Though Cancelling the sprint isn’t a frequent situation. In Scrum framework it’s at the discretion of the Product Owner(PO) to cancel the sprint if PO realize that the sprint goal and plan isn’t adding value to the product. In Scrum only PO has the authority to cancel sprint. After cancelling the sprint, product backlog is updated with latest priorities and value for the product, any work done during the sprint if valuable is reviewed and rest is thrashed or pushed back to product backlog and the next sprint starts immediately.
