Delay of game

[MOFFICIAL]

This is the situation.
Earlier in the game my partner gives a T for delay of game for a player placing the ball on the floor a distance away from where he or I were positioned for a free throw.
Later in the game I whistled a warning for delay on the same team for slapping the ball after it had gone through the basket.
My question is.
Should I have issued a T for delay as they had already been given a T for a delay?
