Oversea-Chinese Banking Corp. has sued a suspect involved in Singapore’s biggest money laundering case, marking the first known case of a lender in the city-state taking action to recover losses.

Southeast Asia’s second-largest bank filed a claim against Su Baolin, a Cambodian passport holder, last month, seeking about S$19.7 million ($14.7 million) mostly from a residential mortgage, according to legal documents seen by Bloomberg. The hearing date is fixed for Friday.
