South Africa [Images] coach Mickey Arthur was fined 25 percent of his match fee for swearing at an umpire during the fifth one-day international between South Africa and New Zealand [Images] in Centurion on Sunday.

Arthur was unhappy when a second interruption for rain came after 19 overs of South Africa's innings, one over short of the 20 required to constitute an innings.

South Africa, who went on to win by five wickets, were well ahead of the Duckworth-Lewis victory target at the time.

A Cricket South Africa media release said South African coach Arthur was found to have breached the International Cricket Council [Images] code of conduct by "confronting an umpire as he was coming off the field".

"It was out of character, his first offence, but swearing at an umpire should not be tolerated," the release quoted match referee Chris Broad as saying.

"There is no place for this sort of behaviour in international cricket. As a coach and therefore a leader of his team he must set the example.

"Arthur has apologised for his actions and I hope that we will not see this unsavory incident repeated."

South Africa fast bowler Charl Langeveldt was also fined 75 percent of his match fee for failing to turn towards the umpire quickly enough when he appealed for the wicket of Hamish Marshall, who was caught behind for three.

It was the second time in 12 months that Langeveldt had been found guilty of the Level One offence, a fact that resulted in such a hefty fine this time.

He also did it in the Test series against the West Indies [Images].

New Zealand's Scott Styris was also found guilty of swearing at an umpire's decision and fined 25 percent of his match fee.
