How to delete photo album from iPhone?

I have an iPhone 4s. I have an old photo album that was added to my phone from an old computer I no longer have. I can't figure out how to delete it. When I open up iTunes it doesn't show that the album is synced to my phone at all. Any suggestions?

Assuming you're running iOS7 - in your photos app tap edit on the top right and select delete on the album that you want to remove.

However it seems like you're running iOS6 so you'll have to resync again:
