Swedish police said they have arrested one person in connection with a deadly truck attack in central Stockholm.
"One person has been arrested who may be connected with the incident," police said in a statement.
Separately, national news agency TT said police had confirmed that four people had been killed in the attack, which also left more than a dozen injured.
Four people have been confirmed dead, while 15 people were injured. Nine people have been left with serious injuries according to police.
Earlier police released an image of man they wished to speak to in connection with the incident. An official has said that the man arrested resembles the man in the CCTV image.
The man has been identified, police say.
Sky News reports that the man was arrested after a member of the public contacted police after noticing the man acting strangely.
A manhunt is still underway for the driver of the lorry.
A police spokesman said: "The driver of the lorry, we have not made contact with him."
Mats Lofving, head of Swedish police's National Operations Department (NOA) said the picture, was taken close to the time of the incident, in the vicinity of the attack.
"I have a picture of a person who has been seen at the location at this point in time. We want to get in contact with this person," he told a news conference.
The grainy image shown by police showed a man wearing a jacket with a dark hood over a bright t-shirt and dark trousers.
Police said there were no indications that an attack was imminent.
Police evacuated people from surrounding buildings, who were required to stay there in the immediate aftermath of the incident.
The Swedish Prime Minister, who earlier said everything indicated that the attack was terror related, has said the country is united.
Stefan Lofven said the Nordic country was united in grief and anger and vowed that hatred would never be allowed to undermine the country's values.
"These kinds of actions will never succeed. We know that our enemies are these atrocious murderers and not each other," he told a news conference.
"Our message will always be clear: you will not defeat us, you will not govern our lives, you will never ever win."
Stockholm's subway service has been cleared to restart but all bus traffic in the city centre remains at a standstill, the public transport authority said.
The incident occurred near Queen Street in Central Stockholm shortly before 3pm, local time.
A vehicle drove onto the pedestrian street Drottninggatan and into a department store building.
Several deaths and injuries have resulted but police said they were unable to confirm the number of fatalities on Friday afternoon.
It is understood the truck was hijacked or stolen from a brewery company Kall Ol.
In the immediate aftermath panic ensued and people fled the area.
Elsewhere, there are reports of a shooting on a separate street in the city. Police are now also investigating this incident.
Towe Hägg, a spokeswoman at Stockholm police command center, said earlier: "Police were alerted at around 2.53pm (local time).
"We have initial information that people are injured and we are here to find out more."
No further reports of gunshots emerged and it is not clear what happened in the second reported incident.
All subway traffic has now been closed down in Stockholm following the attack and trains into the city have been cancelled.
Police have also ordered a lockdown on the city's central train station.
Government offices have been evacuated and all cabinet ministers have been brought to safety.

The European Union has offered Sweden support and solidarity.

"One of Europe's most vibrant and colourful cities appears to have been struck by those wishing it – and our very way of life – harm.
"We stand shoulder to shoulder in solidarity with the people of Sweden and the Swedish authorities can count on the European Commission to support them in any which way we can."

The crash is close to the scene of a terror attack in 2010 when Taimour Abdulwahab, a Swedish citizen who lived in Luton, blew himself up.
The terrorist, who police concluded acted alone, died on December 11 2010 in the Bryggargatan area. No-one else was killed.
Following today's incident, police in Norway's largest cities and at Oslo's airport will be carrying weapons until further notice following an attack in Stockholm on Friday, Norwegian police said in a tweet.
