Police also said that the suspect had sought and been denied permanent residency in the Nordic country and was wanted for deportation.
"We know that he showed sympathies for extremist organizations, among them IS," police official Jonas Hysing told a news conference.
Police also said roughly five other people of interest to the investigation remained in police custody.
The attack occurred in central Stockholm when a hijacked beer delivery truck plowed into a crow, killing four people and wounding 15 on Friday.
The attack was the latest to hit the Nordic region after shootings in the Danish capital Copenhagen killed three people in 2015 and the mass attack in 2011 by far-right extremist Anders Behring Breivik killed 77 people in Norway.
A failed suicide bombing in December 2010 killed an attacker only a few hundred yards from the site of Friday's incident.
