Seven officers of the Kanagawa Prefectural Police were referred to prosecutors on Friday for allegedly falsifying traffic violation tickets and related investigation reports.

Kanagawa police will cancel some 2,700 traffic violation cases that are believed to be based on falsified documents. The police will refund a total of ?35 million paid in fines for the violations.

According to the prefectural police, the seven served on the same squad, and a veteran sergeant was at the center of the misconduct. The remaining six were unable to point out the problem, and falsifying such paperwork became routine.
