FIBA Rules...Violation on the free throw shooter?

[AD]

Hello all...

I referee under the international rules in Canada. I had this play occur on the weekend and I had not seen it in my 12 years of refereeing basketball.

Free throw shooter on his last shot, dribbles the ball a couple of times in preparation to shoot. Picks up the ball and places it in his left hand. The Shooter then gathers to shoot and makes a motion with his Right hand to shoot. All players enter the key from the as to anticipate a rebound but the ball remained in the left hand of the shooter.

I called a violation on the shooter for faking a free throw? Is this correct?

Thanks
