A spectator at the Masters faces the prospect of a lifetime ban from Augusta after disrupting Rory McIlroy's third round with an ill-timed outburst.
As the 36-year-old Northern Irishman prepared to strike his tee shot on the 17th hole, a voice from the gallery yelled, "Give me back my son", while the ball was mid-flight.
The distraction appeared to affect McIlroy's concentration, with his shot veering into the trees.
Augusta National maintains notoriously strict standards of spectator behaviour.
