This old house is located at Székely Mihály utca 12. Prior to the war, this narrow street, then known as Kazár utca in Terézváros, the 6th district of Budapest, was bustling with second-hand stores selling clothing once owned by affluent individuals. Many of these shops were owned by Jews, with synagogues of Erzsébetváros nearby and a Prayer House on Káldy utca. Presently, the Yeshiva of Pest continues to operate at Vasvári Pál utca 5.

On May 5, 1927, two young men entered one of Lipót Diamantstein’s stores, located at Székely Mihály utca 1, seeking to purchase a “börböri” coat (a Hungaricized term for “Burberry,” denoting a premium-quality cloth). However, the seller provided them with a “vipkord” piece (derived from “Whipcord”). Realizing they were being deceived, the men became enraged; in response, the seller directed them to the Turcsányi store, falsely claiming they had genuine “börberi” coats. When Ernő Marosi, the seller at Turcsányi, presented them with a “vipkord” jacket, they assaulted him.

Marosi sought help on the street, and soon other sellers gathered, surrounding the men who brandished knives. In the ensuing altercation, they stabbed Ernő Schwart in the neck, severing an artery. The crowd pursued the assailants, and while fleeing, one of the men stabbed Ármin Reisz, a resident of Székely Mihály utca 12. The two fugitives were apprehended on Király street, identified as 32-year-old Béla Garbács and his 25-year-old brother Gusztáv. Fortunately, both victims survived, although Ernő required several weeks of hospitalization.
