At least two people were killed Friday after a stolen truck plowed into a crowded street in Stockholm, according to Swedish authorities.
Sweden’s Prime Minister Stefan Lofven initially said one person had been arrested in what he described as “a terror attack.”
“The government is doing everything in its power to find out what has happened,” Lofven said in a televised statement. “We are advising the public to be careful and to listen to police broadcasts. According to security police, there are at least two dead in this awful terrorist attack. We are thinking of the victims and their families and the injured.”
Stockholm police later said at a press conference that no arrests have been made.
Police said they had received reports of a truck driving over people on Drottninggatan Street near the upscale department store Åhlens in central Stockholm. Several people died and others were wounded in the incident, police said.
According to police, terrorism can’t be ruled out given similar incidents that have happened elsewhere in Europe in recent months.
“We had no indication that this would happen but it was not unexpected,” Stockholm regional police chief Ulf Johansson said at a press conference Friday.
Police said it’s unclear whether this was an isolated attack or if it’s related to any other incidents.
Police said they have not called in the Swedish military and don’t think that’s necessary at this time. Authorities are working on a national level and using international resources as well to track down the culprit or culprits, police said.
A spokesperson for Spendrups brewery in Sweden confirmed to ABC News that the truck used in the attack was stolen from them.
“We can confirm that the truck was stolen during an unload of products,” Rose-Marie Hertzman, the press officer at Spendstrups, told ABC News. “The driver was just finishing the unload and a man came running up and hijacked the car and drove away.”
Hertzman added, “Our driver is not hurt and we are of course extremely sad to hear about the injuries and the two people confirmed dead.”
The Spendrups truck was distributing soft drinks, beer and water to restaurants and shops, according to Hertzman.
Police said the truck is now in their possession and they are interviewing the original driver of the vehicle. However, authorities are not in contact with the individual or individuals driving the truck during the attack.
Swedish intelligence officials are working to identify the person or people behind the attack.
Police said Stockholm’s Central Station is closed and are urging people to avoid the area around Sergels torg square.
