Drottninggatan

A dozen people were injured in what appeared to be the latest use of a vehicle as a weapon of terror in Europe.

The Swedish Security Service said the attack happened just before 3 p.m. local time. People were seen fleeing the area in panic.

A beer truck was hijacked as it made a delivery nearby, according to the company that owned it. Eyewitnesses reported it being driven at speed along Drottninggatan (Queen Street) before it crashed into the front of a department store.

At least a dozen people were also injured in the incident on Drottninggatan (Queen Street), one of the city's major pedestrian streets, on Friday afternoon.

Swedish Prime Minister Stefan Lofven said it was a terror attack.

One man has been arrested, after police released a CCTV image of a person who may be connected to the case.

In a speech on Friday night, Mr Lofven said Swedish values of democracy and freedom would not be "undermined by hatred".

He also announced the country's border controls had been strengthened.
