Suspected attacker named as Franz Wrousis, 51, a Swiss national

Schaffhausen, Switzerland (CNN) Police are searching for a chainsaw-wielding attacker who injured five people, including at least one seriously, in northern Switzerland.

Police said they do not believe Monday's attack in the historic town of Schaffhausen is terrorism related, but warned the public that the man at large is "dangerous."

The attacker was identified as 51-year-old Franz Wrousis, a Swiss national with no fixed address who lives in a forest, Schaffhausen public prosecutor Peter Sticher said.

Sticher described him as a 190 centimeter-tall (6 feet 2 inches tall) bald white man, while police described him as a man of "untidy appearance."

Authorities are seeking the public's help in locating Wrousis. Schaffhausen police released a photo of him taken before the incident on CCTV cameras. He appears to be wearing a green windbreaker and black trousers, police said. He is carrying a big black bag that may have contained the chainsaw.
