A Chinese woman managed to enter Japan illegally by having plastic surgery to alter her fingerprints, thus fooling immigration controls, police claim.
Lin Rong, 27, had previously been deported from Japan for overstaying her visa. She was only discovered when she was arrested on separate charges.
Tokyo police said she had paid $15,000 (£9,000) to have the surgery in China.
It is Japan’s first case of alleged biometric fraud, but police believe the practice may be widespread.
