Robberies at the Workers' Union Bank

At lunchtime on March 16, 1916, Leonard Gyllenpalm went to the Arbetarringens bank on Humlegårdsgatan and asked to rent a bank safe. Once inside the vault, he attacked the bank employee with an axe, killing him instantly. He also managed to shoot and kill a female cashier. Eventually, the perpetrator was arrested outside the door of Kommendörsgatan 12, where he had been living for a time. Just two years into his life sentence on Långholmen, Leonard Gyllenpalm died due to complications from tuberculosis.
