Rousseff was taken to the OBAN headquarters, the same place where Vladimir Herzog would be tortured and killed five years later. She was allegedly tortured for 22 days by punching, ferule, and electric shock devices. As Maria Luisa Belloque, a cellmate, said "Dilma was shocked even with car wiring." Some ex-military officers have dismissed Rousseff's account, saying that she could not have survived that extent of torture. Later, Rousseff denounced the torture she suffered in court proceedings, citing even the names of those who tortured her, such as Army Captain Benoni de Arruda Albernaz, mentioned by several other witnesses. Although she revealed the locations of some militants during torture interrogation, Rousseff managed to preserve the identities of Carlos Araújo (who would be arrested several months later) and Maria Celeste Martins. Rousseff's name was on a list found at Carlos Lamarca's home, on a list of the prisoners who would get priority in exchange for hostages, but she was never exchanged and served out her sentence.
