STOCKHOLM (CNN) — A man has been arrested on suspicion of terrorism offenses after the Stockholm truck attack is most likely the driver, Swedish authorities said.
Undetonated explosives were reported to have been found inside the stolen truck, which was driven at high speed down a busy shopping street before crashing into a department store.
The attack Friday in the heart of Sweden’s capital killed four people and injured about 15 more. Ten of the injured — nine adults and one child — are still being treated in three different hospitals in the city, the Stockholm County Council said Saturday. Four of the adults have serious injuries.
Police arrested a man north of Stockholm later Friday. “It is likely that it is the driver of the van that has been arrested,” police spokesman Mats Eriksson told CNN. “This however does not exclude the possibility of there being more arrests that will follow.”
A bag of undetonated explosives was found inside the truck, which was stolen minutes before the attack as it made a delivery at a restaurant, Sweden’s public broadcaster SVT reported Saturday.
The explosives, in the form of a homemade bomb, did not properly detonate, SVT reported, citing multiple police sources. The attacker apparently suffered burns caused by the explosives, SVT said.
