The family were flown to Uzbekistan in a specially chartered plane on Friday, but are set to arrive back in Halland in western Sweden already on Monday.

“They are not Uzbeks, according to the Uzbek authorities,” said Marianne Paulsson at Halland police to the TT news agency.

The family will now undergo a new investigation into their application for asylum.

The case gained attention after Falkenberg municipal executive board urged the Migration Board (Migrationsverket) to reconsider its decision to deport the family.

But despite the appeal, the deportation was carried out on Friday in a plane carrying a number of other families.

“The Uzbek authorities have conducted a very thorough investigation and concluded that the family are definitely not from Uzbekistan and are not Uzbeks,” Marianne Paulsson said.

Paulsson explained that the identification documents held by the family were fakes and former places of residence given by them have been shown to be fabrications.

The Migration Court has previously ruled that the family is from Uzbekistan although the Migration Board has said that it believes the family could originate from Uzbekistan, Azerbajdzjan, Turkey, Georgia or elsewhere, Paulsson told TT.

The family will be returned to the Migration Board’s reception unit on their return to Sweden.

Deported people return to Sweden from time to time.
