Deathstroke in the Batcave

Quick question: can anyone verify/debunk that Deathstroke has ever entered the Batcave for me? I'd appreciate it if anybody's capable of doing this, or at least pointing an issue number out to me. Thanks.

To be honest I really don't know but it might be very possible. I know Superman has enter the Batcave along with other members of JLA. I only follow Detective Comics so I'm not sure about Legends or the regular Batman series.
