Hadn't seen this before

I am not a referee, just looking for some education. Was watching a 14u game last night. Team A has ball in front court. Ball gets knocked loose and a mad scramble begins. A team A player inadvertantly kicks the ball and it rolls fast into back court. Another team A player gives chase and stops the ball with his foot just like a soccer player and picks it up. He then dribbled back into front court. There is no way the official didn't see it happen as he followed the player into back court. I thought this was a violation. Please educate me one way or the other.
