The previous year only 194 look-alikes were detained.
The daily De Morgen reports that the figure is on the rise. An explanation is easy to find: forging a passport is proving increasingly difficult. As a result it's easier to impersonate somebody else and use their passport.
Last year 1,419 travellers were stopped at Brussels Airport travelling on a false, forged, stolen or fraudulent passport or ID.
In order to stem the flood the airport is introducing six biometric scanners next year.
Police officer Peter De Waele explains: "The scanners compare proportions on the photo with the actual proportions of the head of the traveller. In future it will also be possible to compare finger prints."
