In a press conference and statement police named the suspected perpetrator as 51-year-old Franz Wrousis, a loner who is thought to live in forests and was not previously known in the Schaffhausen area.
Police confirmed that he attacked staff at an office of the CSS health insurance company in Schaffhausen.
Two people were injured with the chainsaw. It is not yet known how the other three were injured.

Though the man's motive is unknown, it is believed to have been a targeted act against CSS.
Wrousis has two previous convictions for possessing illegal weapons.
Police cannot yet give the all-clear since Wrousis is still on the run, probably armed with the chainsaw and potentially other weapons.
Around 100 police officers and nearly 50 medical staff were involved in the response this morning.
