SINGAPORE: A private banker, caught up in Singapore's money laundering probe linked to 1Malaysia Development Bhd (1MDB), was a key link between the embattled state investor, a Swiss private bank and a Malaysian businessman connected to the troubled fund.

Yak Yew Chee, a senior banker at Swiss-based BSI Singapore, has emerged for the first time as a key figure in Singapore's money laundering probe, according to documents released at Singapore High Court last week.
