A Chinese student and Seven-Eleven employee was arrested Friday in connection with the ¥55 million heist conducted via 7pay, the new mobile payment service launched by Seven-Eleven Japan.

Yu Huiling is the third suspect to be detained in a case police think may be linked to an international crime organization based in China.

Yu, a 21-year-old part-timer at a Seven-Eleven in Tokyo's Chiyoda Ward, is suspected of using stolen IDs for the service to buy around ¥32,000 ($295) worth of 15 items including electronic cigarette cartridges and cosmetics at the convenience store where she worked.
