Union Chancellor candidate Armin Laschet (CDU) spoke of "terror" in connection with the allegedly planned attack on the synagogue in Hagen.

“Terror is a real danger again,” said Laschet on Saturday at an election campaign event in Delbrück, North Rhine-Westphalia.

"Two days ago we saw in Düsseldorf, through information from international services, that an attack on the Jewish synagogue in Hagen was planned."

The police reacted very quickly, said the North Rhine-Westphalian Prime Minister.

“And in the meantime a young man has been arrested and imprisoned, which shows that it was more than just a suspicion.” The police had prevented “another attack on Jews in Germany on Yom Kippur Day, this time by Islamists who probably planned this in a network, ”Laschet continued.

Lawyer wants to apply for a detention test

In the Hagen case, a 16-year-old Syrian is in custody on Friday evening following the decision of a judge.

There is an urgent suspicion against him of preparing a serious act of violence that is dangerous to the state, said the Düsseldorf Public Prosecutor's Office.

The youth arrested on Thursday is said to have denied attack plans during the interrogation.

His lawyer, who had expected his release, announced that he would request a detention review and file inspection.

According to security sources, the decisive reason for the arrest of the 16-year-old youth is said to have been the chat with a suspected supporter of the terrorist organization “Islamic State” (IS) via the messenger service Telegram.

A foreign secret service is said to have given the hint.

According to the public prosecutor's office, an adult offender who is convicted of preparing a serious act of violence that is dangerous to the state faces imprisonment from six months to ten years.

When applying youth criminal law, however, other standards and sanctions apply.

Laschet had previously spoken out to the Bild newspaper in favor of deporting so-called threats.

As Federal Chancellor, he also wanted “bans on anti-constitutional organizations and associations, bans on symbols of hatred and terror, entry and residence bans, expulsions and deportations - as far as possible,” he said.

Baerbock: Monitor top threats around the clock

His rival, Green Chancellor candidate Annalena Baerbock, told the newspaper that there was “no justification, no acceptance, no excuse for anti-Semitism, whether from the right, from the middle of society or Islamistically motivated.” Top threats had to be around the clock be monitored.

The chairman of the parliamentary control committee of the Bundestag, Roderich Kiesewetter, praised the cooperation with foreign services.

Politicians must "ensure that our intelligence services can cooperate on an equal footing with partner services," said the CDU politician to the editorial network Germany (RND).

Terrorism expert Peter Neumann from King's College in London, who is part of Laschet's “future team”, told the RND: “In the cases of prevented attacks that I know of, 80 to 90 percent can be traced back to information from American services. Their possibilities for checking digital communication far exceed what Germany is capable of and what we are allowed to do. "
