1 Dead in Amsterdam coffeeshop "stabbing"

. ()

A man found outside a coffee shop with "life-threatening injuries," possibly caused by a stabbing, has died, according to Amsterdam broadcaster AT5. "He was found bleeding" outside the City Hall on Oudezijds Voorburgwal, police said.

"It could have been a stabbing. It could have been an accident," a spokesman said. "He lost a lot of blood."

One witness, Neil Thompson, said he heard shouting on the street, but did not pay attention to it because it is not uncommon in the area. "When I looked down, I saw a medical team and a man on the street bleeding heavily from his left torso and leg. He had a big gash on his leg," Thompson said.

"He looked dead."

Paramedics worked on the man for "a good 20 minutes," Thompson said. Police confirm the man was taken to an area hospital. His injuries were still considered critical as of 1:30 p.m, but he did not survive through the day.

Investigators have been going in and out of City Hall, in the basement of Oudezijds Voorburgwal 189, and they have also been gathered outside the Green House coffeeshop at number 191 of the same street.

An early report published by Het Parool said witnesses thought the man could be a tourist from a southern European country, based on the way he looked.

Witnesses say the man collapsed on the ground in a pool of blood between 11 a.m. and 11:30 a.m.

One officer working security near the scene thought it was a stabbing based on early information.

Witnesses at the scene said another man left with police, but it is not yet known if he is a suspect, accomplice or witness.
