STOCKHOLM — The 39-year-old Uzbekistan man suspected of plowing into shoppers Friday — killing four people and injuring 15 in Stockholm — was an asylum seeker who had had his application rejected, police said Sunday.

Authorities also said the four victims of the attack had been identified as two Swedish nationals, a British person and one Belgian citizen.

The Uzbekistan national was known to have expressed sympathies toward extremist organizations, including ISIS, and was wanted for deportation from the Nordic country, Reuters reported.

It came as the Swedish department store that was rammed by the stolen beer truck said it was sorry for announcing it was reopening Sunday to sell damaged goods at a "reduced price."

In a statement on its Facebook page, the Ahlens department store apologized "for a bad decision."

The store said its motivation "was born out of the idea of standing up for transparency and not allowing evil forces take control of our lives."

The store said it would reopen Monday "without any damaged goods."

Earlier Sunday police said they had brought in seven people over the apparent terrorist attack outside the department store on Friday, according to Reuters.

Authorities confirmed that the suspected truck-driver was known to security services and described him as a "marginal character."

Speaking at a press conference on Saturday, the head of Sweden's National police, Dan Eliason, said security officials had found an object in the truck that "could be a bomb or an incendiary object."

On Sunday morning ten of the injured remained in hospital, two of them in intensive care, Stockholm authorities told Reuters.

The incident sent shock waves through the country. Sweden's crown princess Victoria held back tears as she left flowers for the victims at the site of the attack on Saturday.

"Sweden shall come out stronger from this, and we get through this together," she told the press and mourners gathered near the department store.

The Swedish TT news agency said city officials planned to move thousands of flowers to a nearby square after an aluminum fence outside the department store threatened to collapse.

The fence was put up to keep people away from the broken glass and twisted metal at the attack site, and to allow forensic experts and police to gather evidence.
