A manhunt is underway in the Swiss town of Schaffhausen after a chainsaw-wielding assailant injured five people, two seriously, in a violent attack. Police say they are not treating the attack as a terrorist incident.

Police identified the suspect and confirmed the weapon he used. The suspect is described as dangerous and bald with an “unkempt” appearance. Measuring about 6ft 2inches in height, he’s believed to be driving a white Volkswagen Caddy.

Police were alerted to the scene just after 10.30 am local time after the suspect entered an office building.

Parts of the old town are sealed off due to a “special situation,” according to police. Ambulance teams and police are on the scene and rescue helicopters are circling overhead, according to a Swiss police spokesperson.
