Switzerland: Man Yelling, "Allahu Akhbar" Stabs 3 in Winterthur

Today in Winterthur, Switzerland, a 31-year-old Swiss-Turkish (dual citizen) man stabbed 3 people at the train station while yelling, “Allahu Akhbar”. All 3 victims were seriously injured. The man was arrested and is identified as Nesip Dedeler. In addition, he had just been released from a psychiatric facility the day before when a doctor judged that he posed no danger.

Swiss police advise the man is known for spreading pro-ISIS propaganda and was associated with a radical mosque, which is now closed.

Switzerland is shocked. The news of a knife attack at the Winterthur train station spread quickly over the entire country. We are also learning more and more about the perpetrator. During the act, the man shouted, “Allahu Akhbar” (God is greater). Investigation shows that the man was active in the Islamist scene. That is confirmed by the Cantonal Police in Zurich.

At the press conference with Government Councilor Mario Fehr and Police Commander Marius Weyermann, more was revealed about the 31-year-old man. The man is Nesip Dedeler (31). His family comes from Turkey. He was naturalized in 2009.

In our own behalf

In this case, Blick is giving the full and correct name of the knife attacker in Winterthur, Nesip Dedeler, and shows it without censorship bars. The authorities, with the Zurich police director as the central voice, describe the act as an “act of terror”. In such a case, we give the name of the alleged terrorist as a contemporary, historical (public) person. 

In 2024, he applied for a renewal of his passport but never showed up, Fehr reports. In August 2024, he left Switzerland and was traveling in Turkey. “Then he disappeared for two years,” said Fehr.

Connection to An’Nur Mosque

Dedeler belonged to a group, from whom several young people were later charged and some convicted. This was first reported by SRF (Swiss Radio and Television). For example, his name surfaced in investigations into the so-called youth group of the subsequently closed mosque, An’Nur. In the notorious mosque, among other things, an imam called for violence against “bad Muslims”.

The Cantonal Police of Zurich confirm that he is a dual Swiss-Turkish citizen. The man’s two brothers have also shown up in investigations as being radicalized. Furthermore, he was sent videos and songs with radical content from the (radical) scene. The suspect has also come to the attention of the authorities for spreading Islamist propaganda and trying to persuade others to join the jihad. “Violating the ban on ISIS. He spread IS propaganda,” Marius Wyermann from the Cantonal Police explains.

Treatment in clinic

The 31-year-old man, according to authorities, was also “psychiatrically disturbed”. On May 25 of this year, he reported to the city police, says Marius Wyermann at the press conference. “He made incoherent statements,” said the police commander. He was admitted to the integrated psychiatric ward in Winterthur (IPW). That corresponds also with observations of a neighbor, who told Blick that on Whitsuntide Monday, police officers were seen at Dedeler’s apartment. On Tuesday, May 26, he left the IPW and was again visited by police and taken back. On Wednesday, one day before the bloody act at the train station, a doctor gave a diagnosis that Dedeler represented no danger to himself or others. He was free to leave the facility………………………………………..
