Malaysian Anti-Corruption Commission (MACC) chief Dzulkifli Ahmad expressed puzzlement over accusations that the graft busters had only gone after low-ranking officers, described as "ikan bilis" (anchovies), but ignored the "sharks and whales".

"Some times I don't understand when people talk about 'ikan bilis', sharks and whales.

"If the action MACC had taken against those with the title of 'tan sri', 'datuk seri' and 'datuk', who are not 'whales and sharks', I don't know what 'whales and sharks' are supposed to be," he said during an interview on TV3's Soal Jawab programme last night.
