BERLIN, Feb. 25 (Xinhua) -- A 73-year-old man died from his injury on Saturday after being attacked by a man who rammed his car into a group of pedestrians in the German city of Heidelberg.
The identity of the attacker was not disclosed and the police said the man had no indication of terrorist background.
The man also injured the other two, a 32-year-old Austrian national and a 29-year-old woman from Bosnia and Herzegovina, according to Deutsche Presse Agentur.
The suspect, reportedly armed with a knife, fled the scene after the attack. But he was later shot and injured by police in a brief standoff.
Local police has now blocked the roads nearby and helicopters were dispatched to take aerial photos of the scene.
German police have been tightening up security after the Dec. 19 attack on a Christmas market in Berlin, which killed 12 people and wounded some 50 others.
Earlier this month, the police carried out a series of raids in Goettingen and arrested two men suspected of planning a terror attack.
