A court in Madrid has ruled that the six employees from the Industrial and Commercial Bank of China will be held in police custody, as an investigation into alleged money laundering continues.
The six from the lender's Madrid branch were arrested after Spanish police raided the bank earlier this week.
ICBC said on Saturday that it has been complying with local laws and will fully cooperate with the probe.
The bank says it will also take measures to protect its legitimate rights.
