Swiss police arrest alleged chainsaw attacker

July 25 (UPI) -- Police in Switzerland said they arrested Franz Wrousis, a chainsaw-wielding suspect accused of injuring five people, on Tuesday.

Authorities caught the 50-year-old suspect in Thalwil, about 6 miles south of Zurich, one day after the attack Monday, Schaffhausen police said in a statement.

Police described Wrousis as a 6-foot-2 loner with an unkempt appearance who mainly lived in forests but visited populated areas. He was convicted on weapons violations in 2014 and 2016.

Police said Wrousis attacked an office building for the CSS health insurance company in Schaffhausen, near Switzerland's northern border with Germany. Wrousis was a customer for the company.

Police said that while Wrousis' motive is unclear, they believe he targeted the insurance company specifically.

Two people were injured with the chainsaw, but police did not yet reveal how the other victims were hurt. It also wasn't made clear whether the pair attacked with the chainsaw were the same victims listed in serious condition.

However, police did say the life of the man most seriously injured is no longer threatened.

Police said the incident is not related to terrorism. Schaffhausen, with a population of 36,000, is about 30 miles from Zurich.
