How to explain the reasons for duplicate accounts?

The reason for the duplicate account only needs to specify which police station it is addressed to, the applicant XXX, gender, age and current residence. Due to some circumstances, he now has a dual account (with two ID numbers on it). Now, due to the reorganization of accounts, it is found that there are dual accounts, and one of them needs to be cancelled. Now, I apply to cancel one of them. Keep the existing account number and ID number, and hope to solve it.
