A leading German newspaper is reporting that authorities believe there is no terrorist motive behind the deadly van crash in Muenster and the driver is believed to be a middle-aged German man who had psychological issues.
The Sueddeutsche Zeitung paper also says the suspect's apartment was being searched for possible explosives.
German officials haven't yet indicated what they think is the motive behind Saturday's crash into a crowd at a popular Muenster bar, which killed three people and left 30 others injured.
At the same time, police say they are checking witness reports that other perpetrators might have fled from the van at the scene of the crash.
Police spokesman Andreas Bode says witnesses told them others left the van after it crashed Saturday afternoon into a crowd outside a popular bar in the western German city. The German news agency dpa reported that witnesses spoke of two others in the van besides the driver.
Bode also said police had found a suspicious object inside the van and were investigating it.
Police have urged people in Muenster to stay inside their homes and avoid the crash scene in the city's historic downtown.
The mayor of Muenster says authorities don't yet know the motive.
Mayor Markus Lewe told reporters that ``all of Muenster is mourning this horrible incident. Our sympathy is with the relatives of those who were killed. We wish the injured a quick recovery.''
The van crashed into people sitting in front of the famous Kiepenkerl bar on a warm Saturday afternoon in the city's historic downtown.
Police say the driver of the van shot himself to death inside the van after the crash. His identity is not yet known.
Germany's top security official, Interior Minister Horst Seehofer, said federal authorities are in close contact with officials in North Rhine-Westphalia state, where Muenster is located, and all are trying to figure out what happened.
