Austrian police say a man stabbed a man to death because he was unhappy with his life and wanted to go to prison.
Officers said the 29-year-old had planned the killing for weeks in order to be imprisoned.
The man was arrested in the western state of Tyrol on suspicion of stabbing another man to death.
Innsbruck police said on Tuesday that the suspect had walked into a police station on Monday in the town of Kufstein, near the German border.
They said that the man, an Austrian citizen, claimed responsibility for the killing.
