A Chinese man has been left stranded in South Korea after his four-year-old son drew all over his passport while on a family holiday.

The man – known only as Chen – tried to board his flight home to China but was stopped by security.

Border officials told the man that he was unable to travel because the scribbles had left him unidentifiable.

The family is believed to have flown home, leaving Chen stranded in South Korea, according to a News.com.au report.

Doubts have been raised on the internet over the photo, with suspicions that the drawing is fake.

The fact that the man’s name, signature and passport number have been made unidentifyable by the drawing has raised suspicions that it is a fake.
