A 39-year-old Uzbek man being held in custody is the suspected driver of a hijacked beer delivery truck that ploughed into crowds in central Stockholm, killing four people, including an 11-year-old girl, and wounding 15 in an apparent terror attack, police said on Saturday. The man, previously known to Swedish intelligence services as a marginal figure with no clear links to extremist groups, is suspected of mowing down pedestrians on a busy shopping street and smashing through a store front on Friday. "Nothing indicates that we have the wrong person, on the contrary, suspicions have strengthened as the investigation has progressed," Dan Eliasson, head of Sweden's national police, told a news conference on Saturday. The man, detained on Friday night on terrorism charges after the attack in the heart of the capital, appeared to have acted alone but "we still cannot rule out that more people are involved," he said. Police raided several addresses in the Stockholm area on Saturday, according to TT news agency and tabloid Aftonbladet, but told Reuters no further arrests in connection with the attack had been made. A Reuters witness saw police wearing protective masks carrying out a search at an apartment in a southern Stockholm suburb. Court-appointed lawyer Johan Eriksson told Reuters he had met with the suspect on Saturday but declined to give further details about his client. Police did not name the detainee, but said he was from the central Asian republic of Uzbekistan and that he had seemed peripheral in intelligence reports. "We received intelligence last year, but we did not see any links to extremist circles," security police chief Anders Thornberg said. Eliasson said there were "clear similarities" to an attack last month in London in which six people died, including the assailant who drove a rented car into pedestrians on a bridge. Vehicles have also been used as weapons in Nice and Berlin in the past year in attacks claimed by Islamic State. There was no immediate claim of responsibility for the attack in Sweden, which until now had been largely immune from major attacks and where many take pride in an open, democratic society. "I think it was just a matter of time, but still one doesn't think it will happen," Cecilia Hansson, a 25 year-old nurse, said. "It's still unreal when it happens this close." Police said they had found a suspicious device in the vehicle, which rammed into the Ahlens department store, but said they did not yet know if it was a homemade bomb, as reported by public broadcaster SVT. Sweden will hold a minute's silence at midday on Monday to mourn the dead. Police said they were maintaining a heightened presence, fearing copycat attacks. Israel's Foreign Ministry put out a message of solidarity with the people of Sweden following the attack. "We wish to convey our condolences to the families of the victims and wishes for a speedy recovery to those injured in yesterday's terror attack in the heart of Stockholm. Israel stands with you at this difficult time. "Terrorism poses a threat to democratic values, culture and way of life and we must combat it together with determination," the ministry said. Due to the current state of relations between Israel and Sweden, the message was not addressed to the government of Sweden, but rather to the families of the people killed and wounded. Swedish Prime Minister Stefan Lofven visited the site of the attack and struck a defiant tone: "All of us feel anger over what has happened, I also feel the same anger, but we also need to use that anger for something constructive and go forward." "We want -- and I am convinced the Swedish people also want -- to live a normal life. We are an open, democratic society and that is what we will remain." Sweden's King Carl Gustaf, who broke off a trip to Brazil and quickly returned home after the attack, addressed the nation in a televised speech from his home at Stockholm's palace. "Those of us who want to help are many more than those who wish to harm us," said the monarch. "Sweden is, has long been and will continue to be a safe and peaceful country." Meanwhile, in neighboring Norway, an explosive device found near the busy Groenland underground subway station in Oslo late Saturday evening forced police to evacuate bars and restaurants, but officials said the device was neutralized and a suspect arrested. Police would not give any details about the suspect, but Police Chief Vidar Pedersen confirmed that the device found Saturday night, initially described as "bomb-like," was an explosive.
