In 2007, Iranian police launched a "Public Security Plan and Moralization Campaign". Many Iranian citizens including many women were arrested and questioned for "un-Islamic" behavior. That same year, Zahra was sitting on a park bench with her fiancé when Iranian police arrested the couple. This was considered by the Iranian judiciary to be a breach of modesty laws because the two were not yet married. They were taken to jail and held in separate cells, and Yaghoub died under custody the following day. Iranian officials claimed that the victim committed suicide by hanging herself. However the lawyer did not accept the claims and requested investigations.
