After the heavy explosion in Ratingen near Düsseldorf, all life-threatening injured survived the second night after the alleged assassination attempt. A police spokesman in Düsseldorf said on Saturday at the request of dpa.

Whether the dead woman discovered in the suspect's apartment is the 91-year-old mother of the 57-year-old suspect is still not conclusively clarified.

Meanwhile, the SPD opposition in the North Rhine-Westphalian state parliament announced that it would request a special meeting of the interior committee because of the case. For example, its domestic policy spokeswoman Christina Kampmann wants to know whether the forces, who were called to a "helpless person" on Thursday, were informed that a violent offender lives there, against whom there was an arrest warrant.

The suspect had previously been visited by a police officer

As it became known on Friday, a police officer had visited the 57-year-old a few days earlier with an arrest warrant. The Ratinger had not paid a fine for bodily injury offenses.

The opposition also wants to know what the suspect's affiliation with the prepper scene is all about. He is also said to be a corona denier. Preppers, derived from the English "prepare", are people who prepare for survival in the event of a disaster.

While the emergency services wanted to help a "helpless person", the suspect may have assumed that he should be arrested. He himself is silent about what is happening. A police spokesman had said on Friday that no one could have expected such a devastating escalation of the operation.

State Interior Minister Herbert Reul (CDU) called on police officers in North Rhine-Westphalia to be particularly cautious on the police intranet: "For the moment, I have only one request: Take good care of yourself and your colleagues!" This is stated in the letter, which is available to the German Press Agency.

"I am deeply saddened by this terrible operation – and, frankly, angry. All forces had only good intentions in mind, they were dedicated to service to society and only wanted to help. But here rescuers and helpers themselves became victims," he writes.

Reul continued: "The alleged perpetrator could be arrested, but that is only a small consolation. There are still so many unanswered questions – first and foremost the question of why?"

A judge had sent the suspect on Friday for attempted murder in nine cases in custody. He is said to have hurled a container of gasoline at the emergency services when they had opened the apartment door and came across a stack of water boxes behind it, with which the entrance was barricaded.

Two police officers as well as seven firefighters and rescue service employees had been hit by a fireball and had suffered some severe burns. Because the mailbox was no longer emptied and overflowing, the landlady had asked the police to check on the situation.

The 57-year-old was a violent offender who had already been noticed for three bodily injuries and against whom two penalty orders had been imposed, the investigators had reported. During a search, the police found PTB weapons in the basement - including alarm shot, irritant and signal weapons - as well as knives and daggers.
