foul on AP throw in

[MikeCapps]

Start of period, A has the arrow. A1 taking the ball out.

B1 holds A2 trying to prevent the throw in. No bonus. A's ball for throw in on the foul and retain the arrow since a foul by either team during the throw in does not cause loss of the arrow.

10 seconds later held ball. A's ball.

Pretty sure I got it right, has it happened once a few years ago, but I had to check the book in my car as soon as tyhe scrimmage was over.
