The college diploma given to a woman who completed her degree using a fake ID here in China has been revoked.

The woman graduated from a vocational college in Henan in 2006.

She had been working as a teacher after finishing her degree a decade ago.

The issue came to light after Wang Nana discovered that her college admission certificate had been stolen in 2003.

Authorities later discovered a woman posing as her used the admission paper to enter college and get her degree.

It's not clear whether the imposter stole the admission form or whether it was someone else who later gave it to her.

This follows a similar case in 2009 which saw a person's ID stolen by a police official, who later used it to enroll her daughter into university.

Her diploma was subsequently cancelled as well.
