The parents of dozens of students attending foreign schools in Seoul were summoned for questioning over suspicions that the students gained admission based on fraudulent documents, prosecutors said Friday.

The parents, including the 39-year-old wife of a lawyer working for one of the country's largest law firms, were questioned about submitting fabricated documents to falsely identify their children as foreign nationals, the prosecutors said.

About 50 to 60 parents are suspected of illegally putting their children in schools for children of foreign residents in the country with fabricated passports and foreign citizenship papers which they bought from a foreign broker.

Also among the parents under probe are chaebol offspring, hospital heads, a golf resort owner and an investment firm head, according to sources well informed of the investigation.

Prosecutors raided three schools suspected of being involved in the admission fraud last week to secure evidence.

However, no money transactions between the broker and the schools have so far been discovered, prosecutors said. (Yonhap News)
