Three adults and a child have died and a teenager has been seriously injured after falling from a seven-storey residential building in the lakeside town of Montreux, in Switzerland.
Police said the victims were all French citizens and members of the same family.
Officers had tried to execute a warrant in connection with the home-schooling of a child shortly before the incident, police said.
In a statement, police identified the people killed as a 40-year-old man, his 41-year-old wife, her twin sister and the couple’s eight-year-old daughter. They said the couple’s 15-year-old son was seriously injured.
“The presence of another person in the apartment at the time of the facts could be excluded at this stage of the investigation,” he added.
Regional police spokesperson Alexandre Bisenz told the Associated Press the five people were found at about 7am on Thursday outside a building near the city’s famed Casino Barriere.
Police said two officers had knocked on the door of an apartment and identified themselves.
“Unable to make contact with the possible occupants, they left the place,” police said. “In the meantime, a witness called the police to report that people had fallen from the balcony of an apartment.”
Montreux is best known as a tourist hotspot and in particular for its annual jazz festival.
Police and emergency teams erected white tents at the scene, and forensics investigators were spotted on the top balcony of the building.
