A suspect was arrested more than two months after a knife attack in Berlin-Wedding.
The handcuffs clicked in the 29-year-old's apartment, the police said on Thursday.
During the arrest on Wednesday afternoon in Wilmersdorf, evidence was also obtained.
The man is said to have seriously injured a 32-year-old thigh with a knife in early August.
Berlin - The police did not provide any information about the possible backgrounds of the crime.
