Further search in German investigation into Solingen knife attack

German investigators again searched the refugee accommodation on Tuesday where the knife-wielding attacker suspected of killing three people at a festival in Solingen had lived.

Authorities were also seeking to interview people who may have known the suspect, a 26-year-old Syrian man identified only as Issa Al H under German privacy rules.

No further arrests were made during the search on Tuesday, according to federal prosecutors who are handling the case.

The suspected terror attack at a city festival on the market square in Solingen stunned the country. In addition to the three people slain in the attack, eight were wounded.

H remains in police custody on suspicion of murder. The Islamic State terrorist group claimed responsibility for the attack, although German authorities have not yet detailed whether the suspect had documented links to the group.

The suspect had remained in Germany after evading a deportation order to send him back to Bulgaria, the country in which he first entered the European Union.

Revelations about the failed deportation attempt prompted a renewed political debate in Germany about refugee policy, leading to pledges from Chancellor Olaf Scholz's government to crack down on irregular migration as well as new steps to deport migrants whose asylum claims have been rejected.
