A cricket official was shot dead outside Newlands Stadium in Cape Town on Wednesday, the Western Province Cricket Association said on Thursday.
The details surrounding the incident, which took place during a test match between South Africa and India, were not clear, said the association's CEO Andre Odendaal.
Luke Fairweather, an official of Alma Marist CC, who managed a Western Province under-age team, had been a guest in the President's Suite at Sahara Park.
"This news defies belief and the cricket fraternity is in deep shock," WP Cricket Association president Mohamed Ebrahim said.
The organisation sent its condolences to the family.
Flags at the stadium will be flown at half-mast in memory of Fairweather during the final day's play.
Western Cape police spokespeople were not immediately available for comment.
