Insurer Alico Japan said Thursday it had received by the previous day about 2,700 inquiries into credit card fraud in connection with the reported leak of credit card data of some of its customers.

Alico Japan, affiliated with American International Group Inc., first announced the suspected leak and abuse of customer credit card data last week.

On Monday, the insurance firm put the number of credit card fraud inquiries at about 2,200 as of Saturday.

The pace of inquiries is dropping but "we can't say it has completely stopped," said an Alico Japan official. Alico Japan has pledged to shoulder any confirmed losses to customers in connection with the leak.
