Well hello there.

[Dragonstrike]

*Materializes behind them with a rougish grin on their face*

I'm a gentleman and scholar of many trades, so thievery is not the only skill I have under my belt.

*They then hold up Absol's Pokeball, shaking it meanfully in front of them*

But it is the one I enjoy employing the most, Agent! Until we meet again~!

*Instantly Vanishes, leaving no trace or connection of his appearance behind*

Except a pair of red eyes gleam in the shadows mere moments later.  Absol had known that something like that was going to happen.  Again.  This is why the agent kept plenty of spare pokeballs on hand, after all.  Not the first time he's dealt with pickpockets, and he knows how to hide things on his person to keep them from being stolen.

(Let's just leave it at that so as not to derail things too much)
