About 10 people remain in hospital after a deadly Friday truck attack in Stockholm, local media reported Saturday, citing the city's administration.

Axar.az reports that on Friday afternoon, a stolen truck rammed into a crowd on a major pedestrian street in Sweden’s capital, Stockholm. At least four people were killed and over a dozen were injured as a result.
"Six of the victims, hospitalized after the attack, were dismissed from the hospital back home. Nine people still remain in hospital, in particular, eight adults and a child," the administration told Radio Sweden (Sveriges Radio).

So far, police arrested two men on suspicion of being involved in the deadly attack.

Swedish Prime Minister Stefan Lofven said the attack was most likely an act of terrorism.

The investigation is underway.
