This ought to answer your question, it comes from Rule 10.
Art. 20. Delaying the game by preventing the ball from being promptly
made live or by preventing continuous play.
A.R. 10. After a field goal by B1 with two minutes left to play: (a) B2 reaches through
the end-line plane and slaps the ball from the hands of A1 or touches the ball as it is
passed along the end line after the score; or (b) after a warning, B2 prevents the ball
from being promptly put in play by slapping the ball away. RULING: In (a) and (b),
an indirect technical foul shall be charged to B2 for delaying the game. When A1, in
making the throw-in, reaches through the end-line plane into the playing court and
B1 slaps the ball from the hands of A1, without B1 breaking the plane above the end
line, the ball becomes live and B1 has not committed a violation.
