The suspect, who was armed with a knife, then fled the scene and was later stopped by a police patrol. He was shot by an officer following a short standoff and was taken to the hospital with serious injuries.

The car used by the suspect was a rented one and had Hamburg vehicle registration places, the media report. Police have not identified the suspect so far, and his motives also remain unclear. However, police say they have no evidence proving that the incident was a terrorist attack, dpa news agency reports. The suspect reportedly acted alone.

A video has surfaced on Twitter showing the man’s standoff with police. RT has worked to verify the Twitter video, collaborating it against images and information from local reports.

German police dismissed media reports that the suspect could be mentally ill. Police spokesman Norbert Schaetzle called such reports “speculation” and stressed he could not “confirm” them in comments to Germany's N24 TV Channel.

“We are working on the identification of the suspect right now… and on establishing his motives,” he said. He added that there was “no evidence suggesting that it was a terrorist attack."
