On Thursday, the German Police pursue the murder and attempted murder investigations after an attack, targeting a synagogue in the city of Halle, left two people dead.

Police searched a residence in Benndorf to the east of Halle and towed away a car in nearby Landsdorf, as investigations got underway following the attack on Wednesday.

Federal prosecutors, who have taken over the case, said evidence had been secured at the residence.

It is reported to be the home of the alleged perpetrator, who has been named by the authorities as Stephan B, and his mother.

A spokesman for the prosecutors’ office in Karlsruhe said B had not previously come to the attention of the authorities as a right-wing extremist.

Investigators are probing whether he had accomplices.

Federal prosecutors see the crime as motivated by right-wing extremism and anti-Semitism, as such posing a threat to national security – a reason commonly given for federal investigators to take over cases.

“He planned to kill people,’’ an investigator said, noting that Stephan B had been unable to implement his plans in full.

Prosecutors are working on charges of murder and attempted murder.

No details were provided on the condition of the 27-year-old man, who was apparently injured when he was detained after being involved in a road accident as he fled in a stolen vehicle to the south of Halle.

His friends and relatives are being probed, the investigators said.
