OOPS! 5 fouls on player who is shooting free throws

[WAZebra]

My partner last night told me about a situation that happened to her. Player from team B fouls a player from team A. It is the players 5th foul but the player that fouled is allowed to remain in the game. Team A is not in the bonus yet so they inbound the ball, take a shot attempt which is rebounded by team B. Team B goes down court to their end and the player who has 5 fouls is fouled in the act oof shooting. After the player shoots and makes the first of 2 free throws the table informs the officials that that player should not be in the game. What would you do?
