A 22-year-old female student was arrested on Wednesday for her involvement in several cases of medical certificate forgery.
In a statement, the police said the suspect is believed to have sold forged medical certificates to other students, who in turn submitted them to their respective schools to skip classes.
The students had contacted the suspect through social media and subsequently arranged to meet up with the suspect to purchase the certificates, which fraudulently carried the letterheads of legitimate clinics.
A police report was lodged after a teacher exposed the ruse while trying to verify the students' medical records on suspicions about the certificates' authenticity.
The suspect was arrested in the vicinity of Ang Mo Kio Avenue 9 around 10.30pm on Wednesday, and a stack of forged MCs found in her home were seized.
Investigations against the suspect as well as the students involved are ongoing; preliminary findings show the suspect had sold the forged MCs to at least 30 students between March and May this year.
The offence of Forgery for the Purpose of Cheating under Section 468 of the Penal Code Chapter 224, carries a maximum jail term of up to 10 years and a fine.
