Two shots were fired as hundreds of people were queuing outside a restaurant in the square. The man, who was wounded in the foot by the second shot, was arrested late on Friday night.

Initial reports stated that the police fired two warning shots. How the second shot hit the attacker was unclear, according to police information officer Petra Sjölander.

“This is a matter for the police officers in charge of the investigation,” she said. The incident, which occurred a few minutes after midnight on Friday, was witnessed by Josefin, 21, and Lidia, 20, from the East Restaurant’s open-air patio.

“We first heard a bang, like a firecracker, and turned to look,” they told the TT news agency.

“We saw a man, about 35 years old, acting aggressively and waving a knife about. Then there was another shot and there was blood coming out of his foot. It was horrible,” added Josefin.

The shots were fired where Biblioteksgatan enters Stureplan. Hundreds of people were dining outside the restaurant at the time; many more were milling around or passing by.

Petra Sjölander confirmed that the man threatened the police with a knife. They told him to put down the knife, but he refused and moved closer to them.

The officers backed away towards the restaurant, but then moved into empty Biblioteksgatan. That’s when the first warning shot was fired, she said.

After the second shot, two security guards approached him from behind and overpowered him. No one else was injured in the shooting and despite a large police presence on the scene, the partying continued far into Saturday morning.
