Swiss Jews are planning a vigil after a 50-year-old member of the Orthodox community in Zurich was stabbed Saturday night in what police say may be a hate crime.

The 50-year-old man who was stabbed is now hospitalized after suffering life-threatening wounds, according to Tachles, a Swiss Jewish magazine.

A 15-year-old male suspect was arrested at the scene, in the center of Zurich a few minutes’ walk from multiple synagogues. A first responder told Blick, a Swiss news site, that the teenager laughed while he was arrested. The site and accounts in Orthodox media reported that witnesses said the suspect made Islamist statements and antisemitic comments during the attack.
