Police in Sweden have arrested a man they strongly suspect was behind a truck attack that killed four people.
On Friday, police say a person hijacked a beer truck and plowed through a sidewalk full of pedestrians in Stockholm. About 15 others were injured.
Authorities issued photos of a person of interest Friday evening. They said Saturday they had a 39-year-old Uzbekistan-born man in custody, but they didn't say if he was the person in the photos. A name hasn't been released, but one official said the man had been on authorities' radar for a while.
Sweden's prime minister offered condolences to victims' families.
"We are determined never to let the values that we treasure — democracy, human rights and freedom — be undermined by hatred," Prime Minister Stefan Löfven said.
Many noted the similarities to the March 22 attack in London, where a man drove a car into a sidewalk near Parliament, killing five before police shot and killed him.
