How would you handle?

[Johnny Ringo]

Late in the game (under 10 seconds) ... Team A is behind and scores a basket to pull within 4.

While B1 has the ball and looking to inbound A1 signals for a timeout. Nothing granted. A1 again signals for a TO and even is heard saying "timeout!"

Team A did not have any TOs left. The official (did not know team A was out of TOs) granted the TO granted the second request.

Question: If you knew Team A did not have any TOs left, do you grant the timeout? And obviously know this will be a tech on Team A or do you just continue play?
