GOALKEEPER RELEASING THE BALL IN INDOOR PLAY

Question:
In indoor my goalkeeper caught the ball, instead of throwing it in, he decided to throw it on the ground and kick it. The ref called a direct kick because he threw the ball outside the 18. The refs explanation is that the goalkeeper has to put the ball on the ground inside the 18 and then can dribble it out and kick it is this true? We’ve never been called on this before and I think he made a mistake on the call.

USSF answer (March 5, 2012):
If it is truly a rule, it must be something local. The only alternative is that the referee has been abusing illegal substances.

In indoor, when the goalkeeper catches a ball during live dynamic play, he or she has 5 seconds to get rid of it in their half of the field or give up possession. They can throw it, kick it, dribble it, or whatever, but when the 5 seconds are up they must not still be in possession of the ball by hand or foot in their own half of the field or it is a direct free kick from where they’re at. (ALL kicks in indoor are direct free kicks)
