Stockholm: Hundreds of people have been evacuated following a chemical leak at a laboratory in Stockholm, police said, adding there is a risk of an explosion, local media reported. At least four people have been hospitalized.
The incident took place near the Karolinska Institute, one of the largest and most prestigious medical universities in the world. The institute lies within the Stockholm urban area.
The Royal Institute of Technology and several private companies were also affected, according to information from the Aftonbladet newspaper.
The chemical leak reportedly started on the seventh floor of the building in a laboratory area near the Karolinska Institute.
“There has been a discharge of gas in this room. It is probably the chemical toluene. In concentrated form it constitutes a fire and explosion hazard,” police spokesperson Sven-Erik Olsson told Aftonbladet.
Rescue services, police and several ambulances are at the scene, the paper added.
An emergency team, wearing protective suits and gas masks, has entered the building to determine the leaked substance.
