Stockholm terror attack suspect arrested after four deaths

A man has been arrested on suspicion of a "terrorist crime" following a truck attack in Sweden's capital city.

Speaking on behalf of the Swedish Prosecution Authority, Karin Rosander said the person was being questioned "on suspicion of a terrorist crime through murder".

Four people were killed and 15 others were wounded after the hijacked beer truck drove through a crowd before crashing into a department store in central Stockholm on Friday afternoon.

Local officials say eight adults and one child remain in hospital.

On Friday, a photo was a released of a man police wanted to talk to about the attack and just hours later they said a man who "matched the description" had been detained.

Police have said the suspect is "likely" to have been the driver of the hijacked truck.

Swedish media reports that the man held by police is a 39-year-old from Uzbekistan.

Meanwhile, the head of Sweden's security agency, Anders Thornberg, said he could not confirm reports explosives were found in the truck.

Speaking of the attack, Sweden's Prime Minister Stefan Lofven said: "These kinds of actions will never succeed. We know that our enemies are these atrocious murderers and not each other.

"Our message will always be clear: you will not defeat us, you will not govern our lives, you will never, ever win."

Security at Swedish borders has been tightened and flags are to be flown at half mast in a mark of respect to victims.

Sweden's king and queen have cut short a royal visit to Brazil and are expected to return home later on Saturday.

The brewery which owned the truck said a masked hijacker had stolen the vehicle as it made a beer delivery at a tapas restaurant. A spokesman added that the delivery driver was unharmed.

It travelled down Drottninggatan - known in English as Queen Street - where pedestrians doing their shopping were sent running for their lives.

Glen Foran, an Australian tourist, said: "I turned around and saw a big truck coming towards me. It swerved from side to side. It didn't look out of control, it was trying to hit people."

The truck eventually crashed into the pillar of the Ahlens department store, where the bonnet started burning.

Late into the night, forensic police were collecting evidence from the stolen vehicle, which remains at the crash site.

Officers have said there was no indication an attack was imminent and no group has claimed responsibility for the attack.
