A man has appeared in court for allegedly insulting former president Nelson Mandela during a Potjiekos competition at Sun City near Rustenburg, North West police said on Tuesday.

Benjamin Burger (46), a shareholder of the security company hosting the competition at the hotel, allegedly played a remixed version of the national anthem on Saturday, Commissioner Lesetja Beetha said in a statement.

"It is alleged that during the competition he played a CD... containing remixed lyrics of the national anthem, and people who attended the event listened to the song Nkosi Sikelel' iAfrika, which continued to say Nelson Mandela is a k****r."

One of the people attending the competition reported this to the hotel manager, who informed the police.

Burger ? apparently a main shareholder of the Falcon Security Company which provides security services at the Sun City hotel ? was subsequently arrested and released on bail of R1500.

He appeared in the Mogwase District Magistrate's Court on Tuesday on a charge of crimen injuria.

The matter was postponed to 11 December.
