Four people have been injured after a shooting incident in Berlin early Saturday, police said, adding that a manhunt was under way for the unidentified assailants who fled the scene.
German media reported heavily armed police officers were deployed to the scene in the Kreuzberg district.
The four injured were aged between 30 and 42. and were shifted to a hospital. One man was pulled from the Landwehr canal, reportedly with a gunshot wound to the leg.
The city’s attorney general said the incident could have been carried out by members of rival organised crime gangs.
A murder investigation team has taken over the investigation.
Residents alerted the police after hearing gunfire. Police said they did not know how many perpetrators might be involved.
German media showed gunshot damage to a doorway of a building opposite the headquarters of the Social Democratic Party (SPD).
The SPD is one of the two major contemporary political parties in Germany along with the Christian Democratic Union of Germany.
Mass shootings are a rare occurrence in Germany.
In October last year, a far-right attacker shot and killed two people in the eastern city of Halle after trying to get into a packed synagogue with home-made weapons.
In July 2016, a teenager used a pistol bought illegally online to kill nine people in a shooting spree at a Munich shopping centre, before turning the weapon on himself.
Most recently there was an attack by about 10 men on a ground-floor flat and a car in Kreuzberg after a 29-year-old was shot.
