How do I delete a container that shows no blobs, but won't let me delete it because points to a vhd

I am trying to delete storage accounts. However, Azure is not allowing me to do that:

* The vm was deleted from the account, now I only have the disks, but they still show as attached to the non-existing machine. When selected, the option to delete is grayed out.

* I go into storage to delete the storage accounts and when trying to delete, I get:

• Storage account luislabstor01 has 1 container(s) which have an active image and/or disk artifacts. Ensure those artifacts are removed from the image repository before deleting this storage account.

* Tried deleting the container, and get:

• Blob 'LEVlabad01-LEVlabad01-2013-06-19.vhd' is in use as virtual machine disk 'LEVlabad01-LEVlabad01-0-201306192202090391', so the blob cannot be deleted.
