Injured taken to hospital during an altercation involving several people in the Kreuzberg district, according to police.
Four people were injured in a shooting in the German capital, Berlin, in the early hours of Saturday, police said, adding that a manhunt was underway for the unidentified assailants who had fled the scene.
A police spokeswoman said the four injured were taken to hospital after the altercation involving several people in the Kreuzberg neighborhood, adding that there was no indication of a political motive.
Armed police searched the area near the headquarters of the German Social Democratic Party (SPD), on foot and by helicopter.
Three of the injured were found in an alley, the fourth was pulled from a canal in the area and apparently sustained a leg injury.
Mass shootings are rare in Germany.
In October last year, a far-right attacker shot and killed two people in the eastern town of Halle after trying to break into a synagogue filled with homemade weapons.
In July 2016, a teenager used a gun illegally purchased online to kill nine people in a shooting at a Munich shopping center, before turning the gun on him.
More recently, around ten men were attacked against a ground floor apartment and car in Kreuzberg after a 29-year-old man was shot dead.
