A man was arrested Friday on suspicion of illegally obtaining the My Number information of a female executive he was working for, the police said.

Shuhei Egawa allegedly copied an image of the woman's My Number notification card, which she had stored on her computer, and saved it to his own computer via the company's internal network on Feb. 26.

The arrest is likely the first related to the law prohibiting the acquisition of a My Number ID by theft or trespassing since the law took effect in October 2015, a police official said.
