BERLIN (Reuters) – A German driver who rammed a crowd of shoppers in Heidelberg, killing one man and injuring two others, has no apparent link to terrorism and has refused to answer questions about the incident, police said on Sunday.

The 35-year-old suspect, who was chased and shot by police and later operated on in a hospital in the southwestern German city for his wounds, has been formally arrested, a joint statement by police and the public prosecutor said.

On Saturday evening, local police issued a denial by Twitter that the man had a migrant background after a wave of tweets from Germany and abroad claimed he was a refugee and that officials were not admitting this.

Germany has taken in over a million migrants in the past 18 months and reports of crime among them have alarmed voters.

The victim was a 73-year-old German man, while the two injured people were an Austrian man, 32, and his Bosnian female partner, 29, the statement said.

“Based on investigations so far, there are no signs of a terrorist or extremist motive for the crime,” it said. “During his first interrogation, (the suspect) made no response to the accusations.”
