Can anyone tell me where the idea that methane is destroying the ozone layer comes from?

I’ve seen it mentioned in a few places now, but I haven’t been able to find the source.

Thing is, the idea doesn’t accord with anything I understand about what goes on up in the stratosphere. Is there a scientific paper out there somewhere that’ll show me how methane promotes ozone depletion?

Come on people! Help me out here. Mail me a link.
