The incident triggered a "major operation" in the city's St Pauli district, police said on X, formerly Twitter.
"The attacker was injured and is currently receiving medical treatment," they added.
According to a police spokesman, there was no indication that the incident was linked to the Euro 2024 clash between Poland and the Netherlands taking place later on Sunday.
The attacker "came out of a pub with a pickaxe and a Molotov cocktail and threatened the police", the spokesman said, adding that the suspect was shot in the leg.
The incident took place near the Reeperbahn station, more than a kilometre away from the city's official fan zone.
