Stockholm attack: 'Suspect device' in Sweden crash lorry

Swedish police have confirmed they discovered a suspect device inside the lorry which was driven into a Stockholm department store on Friday.

The device was found in the driver's seat, National Police
Commissioner Dan Eliasson said, but it was not known whether it was a bomb.

Mr Eliasson also said the suspect in custody was from
Uzbekistan, 39, and known to security services.

The hijacked lorry was driven into Ahlens department store
 in the capital.

Four people were killed - 10 remain in hospital, including a child. Two are in intensive care.

Late on Saturday, police in the Norwegian capital, Oslo,  
found a"bomb-like device" in the Gronland district of the city and detained a man.

An area has been cordoned off while investigations continue,
although according to a tweet from the city police the device did not appear to have "large potential for injuries".

What do we know about the Stockholm suspect?

The suspect, who was not named, was known to the 
security services.

However, he had only been seen as a "marginal character",
 Mr Eliasson said.

The head of Swedish security police, Anders Thornberg,
 said the suspect was "a person who has previously figured
 in our intelligence flow".

It is not clear if the suspect was resident in Sweden.

Mr Eliasson said police had reason to believe the suspect 
was the man behind the attack.

But he added: "We still cannot rule out that more people are
involved."

On Saturday, there were reports of more police raids in Sweden.

However, police told Reuters they had not made any further

arrests.

Was there a bomb in the lorry?

Police say it is too early to tell what the "technical device" 
in the lorry was - only that "it should not be there".

"I cannot say at this stage that this is a bomb or some sort 
of flammable material," Mr Eliasson said.

"We are doing a technical investigation."

What is the Swedish government doing?

Swedish Prime Minister Stefan Lofven has called it a
 terrorist attack, with borders tightened at his request.

"Terrorists want us to be afraid, want us to change our behaviour, want us to not live our lives normally, but that is what we're going to do."

"Terrorists can never defeat Sweden, never," Mr Lofven said.

"We're also determined to continue to be an open society; a
democratic society."

The mayor of Stockholm, Karin Wanngard, reiterated 
that Stockholm was open.

"This is not an attack that's about the colour of your skin,"
 she said.

"We can show that with good integration, with an openness and a friendly behaviour, we are stronger together and it doesn't matter where you come from."

Sweden's king, Carl XVI Gustaf, said: "We are all shaken
 by what has happened."

He added that those "who want to help, are more than
 those who want to hurt us".

"Unfortunately we've experienced many acts of violence before and we have coped and we will now too."

There will be a minute's silence in Sweden at midday on Monday to commemorate the dead.

Has Sweden experienced similar attacks before?

Sweden has generally low crime rates, and has been
 ranked as one of the safest countries in the world.

In 2010, two bombs detonated in central Stockholm , 
killing the attacker - an Iraq-born Swedish man - and injuring two others.

In October 2015, a masked man who was believed to have far-
right sympathies killed a teacher and pupil in a sword attack.

In February, US President Donald Trump cited a non-existent
terror attack in Sweden, and blamed it on the country's
 asylum policy - baffling many Swedes .

Sweden has taken in nearly 200,000 refugees and migrants 
in recent years - more per capita than any other European country.

However, there was a drop in numbers last year after the country introduced new border checks.

Separately, Sweden is believed to have the highest number 
of Islamic State group fighters per capita in Europe.

About 140 of the 300 who went to Syria and Iraq have 
since returned, leaving the authorities to grapple with how best to reintegrate them into society.
