I'm sorry to take your time up with this, but I can't find an answer in the rules or case book so I hoped one of you could.

Visitors are inbounding the ball along the sideline following a charged timeout. The administering official bounces the ball to the thrower and steps away. A teammate of the thrower running inbounds parallel to the sideline reaches across the plane and tries to take the ball, which is still being held out of bounds by the thrower. The thrower does not let go of the ball.

Is this a throw in violation?
