Three people have reportedly been shot dead in a car park near a popular Swiss tourist destination.

The bodies were found in a car park near a train station in the Swiss Alps town of Wilderswill on Monday morning.

Police said they had been alerted to the presence of the bodies in the town near the popular tourist destination of Interlaken at 7am, but gave no further details.

Local media said they were killed in a shooting and police were carrying out a forensic search of a hotel balcony that overlooks the car park.

Residents in the area told the Berner Oberlaender newspaper the shooting was linked to a family dispute, and that a man had first shot his wife and child before turning the gun on himself.

Police said one body had been found inside a car and the two others near the vehicle.

Police blocked off a large area around the crime scene, and train carriages were reportedly moved to block visibility of the scene from a nearby school.
