A man has been arrested after a lorry struck pedestrians during a "terror attack" in central Stockholm, police have said.

Four people were killed and 15 others were wounded after the hijacked beer truck drove through a crowd before crashing into a department store. Emergency services said children were among those hurt.

Police say the man they have detained is someone "whom we are particularly interested in" - and detectives claim he was "in the vicinity" of the incident.

However, investigators added they are still looking for the driver of the truck - and a nationwide manhunt is under way.

Sky sources say a suspect is thought to have run towards an underground station following the crash.


Sweden's Prime Minister, Stefan Lofven, has described Friday afternoon's assault as a terrorist attack.

He told a news conference: "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."

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 but shocked.

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, told the Reuters news agency: "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 hood 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.

The European Commission tweeted: "An attack on any of our Member States is an attack on us all."

A spokesman for German Chancellor Angela Merkel said: "Our thoughts go out to the people in Stockholm, to the injured, their relatives, rescuers and police. We stand together against terror."

The underground in Stockholm has reopened, although the public transport authority said trains would not be stopping at the two stations nearest the location of the attack.
