Investigators are trying to make sense of “confused” statements made by a man who killed a teacher and injured children as he ploughed into a group on a school trip in Berlin, the city’s mayor said on Thursday.
The incident on a popular shopping street in the centre of the Germancapital left six people with life-threatening injuries and another three seriously injured. Some 14 school children were injured.
The driver, a 29-year-old German-Armenian who lives in Berlin, was detained swiftly after his car came to a halt in a shop window.
Berlin Mayor Franziska Giffey said that, by Wednesday evening, authorities had determined that it was an “amok act by a really seriously psychologically impaired person.”
She told public broadcaster RBB Inforadio on Thursday that investigators are working to determine the context and what if anything else influenced him.
They are also “trying, with the help of a language mediator, to find out more from the partially confused statements he is making,” she added.
Berlin’s top security official, Iris Spranger, wrote on Twitter that “according to the latest information” the attacker may be a “mentally impaired person.”
He said on Wednesday that posters were found in the car in whic the driver “expressed views about Turkey.” But she said there was “no claim of responsibility.”
Ms Giffey said authorities don’t yet know whether the posters have any connection to Wednesday’s incident.
Police spokesman Thilo Cablitz told local RadioEins that the driver had previously been known to police “but not from the ideological or politically motivated area.” He didn’t elaborate.
The regional government in central Hesse state said that the students hit on Wednesday attended a 10th-grade class - ages roughly 15-17 in Germany - in the town of Bad Arolsen. Another teacher was among the seriously injured.
The car ploughed into pedestrians close to the site of a 2016 attack in which an Islamic extremist drove a commandeered truck into a Christmas market, resulting in 13 deaths.
Ms Giffey said Wednesday's crash "reopens deep wounds and traumas" associated with that event.
