The third day's play between Pakistan and South Africa was stopped for nearly five minutes before lunch as Pakistan captain Misbah-ul-Haq complained to on-field umpires Rod Tucker and Ian Gould about the misbehaviour of the spectators. Tucker and Gould talked with match referee David Boon.
Soon after, two security officials removed Siddique Amin and Mushtaq Amin from the stands.
"Two individuals were shouting comments in contravention of the ICC anti-racism code which prohibits the use of language that is offensive, insulting, humiliating, intimidating or vilifying," a Dubai Sports City spokesman said.
"The Pakistan captain followed the correct protocol ... venue security was informed and the two individuals were identified and removed from the venue."
Siddique, who hails from southern port city of Karachi and works in Abu Dhabi, said he didn't abuse or pass any insulting remarks to the Pakistan team.
"I was just telling Misbah to include Younis Khan in the one-day team," Siddique said outside the stadium. "We didn't shout any insulting remarks or hurled any stones at them."
Khan missed out again when the ODI team was named last weekend, and expressed his surprise on Monday.
Siddique said Misbah could have been frustrated as South Africa took a huge first-innings lead of 418 runs after Pakistan was bowled out for 99 in the first innings.
"Maybe he got frustrated and took out his anger on us," he said.
