Shabtai was born to Chaim and Pesya nee Horowitz, March 17,1922 in Lvov Poland to a Zionist family; elder brother to Pnina and Esther. He made Aliyah with his fatherף; the family arrived shortly after and settled in Haifa. Pesya was a pharmacist and they established a cosmetic products distribution business. Shabtai studied at “Workers’ Children School” then transferred to “Netsach Yisrael” School. He was a smart committed student, who made many friends. His nationalistic views brought him together with Azriel Livnat, David Holianski and Menachem Luntz, and they joined Beitar. Shabtai was dominant in the group. After elementary school, he began studies at the Haifa “Hebrew Re’ally School”, expressing his nationalist outlook publicly, and his membership in Beitar became known. His father was summoned to the principle with Shabtai and told that politics had no place in school. Despite being a good student, Shabtai was definitively suspended and joined David Holianski at “Saint Lucas English School”. Their goal was to thoroughly study English, and continue at an English Naval academy. They weren’t accepted at Beitar’s Naval School in Tchivetivekya Italy, being under-aged. Shabtai joined Etzel, and after the split joined Lehi. He learned preparation of mines, guided by Yehushua Cohen. This became his area of activity. He lay a large road-mine which he detonated while a British Police truck passed on its way to CID HQ. This operation was synchronised with two assassinations in Haifa that day, retribution for the British killing Elisha in Tel-Aviv. During the attempt to rescue Baruch – mortally wounded – Mosha’le Bar-Giora and Shabtai (wounded) arrived at Menachem Luntz’s Yavniel house. On the April 6, 1944 morning, a large force of policemen and soldiers surrounded the house, because of information from the Hagannah. The force broke into their hiding-place. In a doomed battle, after their ammunition ran out, except a single bullet saved by each to avoid being captured alive. They fought, and were killed. Shabtai was buried in Tiberias. During the funeral, merchants of Tiberias closed their businesses honouring the procession and joined the funeral.
