Stockholm - Swedish National Police Director Dan Eliasson announced today details of the ongoing investigation into the recent terrorist attack carried out in this capital, after which a suspect of Uzbek origin was arrested.

A stolen truck from the brewery Spendrupsm crashed into pedestrians in the boulevard in Drotningttatan on April 7 and then crashed into a shop window at a mall in the center of the city.

According to Eliasson, the 39-year-old detainee, suspected perpetrator of the attack that caused the death of four people and wounds to 15 on Friday, is an asylum applicant that had been difficult to deport from Swedish soil, due to the situation in his original country, although there is an expulsion order that has been in affect for months.

'It is difficult to deport people to some countries that do not accept its citizens' return, or if we deport them by force, they are at risk of being punished,' said Eliasson about the social-political situation in Uzbekistan.

According to records, the possible perpetrator arrived in Sweden in 2014 and although he remained in the Nordic country for four years, he was never fully adjusted to the customs and ideology of his new destination.

Due to that fact, his asylum application was denied in June, 2016, the same year when he was notified that he should abandon the country voluntarily and in February, 2017, the police issued a search warrant that is still valid.

Even so, Border Police Chief Patrik Engström recognized today publicly that even in case of finding the Uzbek citizen on time, the actual possibilities to make the warrant effective or arrest him are 'very little.'
