Both Players are in Control of Ball = Foul or Jumpball?

[pljson]

I've never gotten a definitive response either way. Here's the scenario:

Offensive player is dribbling with his back turned to the defender. Offensive player then picks up the dribble. While attempting to pass and with his back still turned, the defender proceeds to grab the ball from behind and pin it against the body (stomach/chest) of the offensive player.

Is this a foul or jumpball/choose situation?

Thanks for the help.
