The Custody Suite / the Public Prosecutor's Office (Kaszubska / Stoisława Streets)
On 17 December 1970, at around 4:00 p.m., some of the street demonstration participants moved from the Party and militia headquarters towards the Voivodeship Custody Suite, the Voivodeship Public Prosecutor's Office and the army barracks located nearby. A fire was started at the door to the Public Prosecutor's Office, but the attack was forced back using standpipe water and tear gas. As the soldiers fired their guns, several people got injured. According to some witnesses, this was when Zbigniew Semczyszyn, a 23-year-old worker, lost his life.
