“The RM22 million involved 98 bank accounts across six banks,” he said at a press conference at the MACC headquarters.

Meanwhile, MACC deputy chief commissioner Khusairi Yahaya said 21 people had been arrested in the investigation so far, including eight company directors, 12 bank officials and a member of the public.

Previously, a MACC source said the commission had received complaints about bribery involving banking institution officials who allegedly facilitated and approved personal loan applications for a financial consultancy company.

The source said these officials were believed to have received bribes from the firm, which prepared documents purportedly containing false information about clients applying for personal loans.

The agency is believed to have raided 24 locations, including residences and offices in the Klang Valley since last week, in an operation codenamed Op Sky.
