Samar Badawi, sister of jailed Saudi blogger Raif Badawi and former wife of Waleed Abu al-Khair, has been arrested, Deutsche Welle reported.
Amnesty International has said her arrest may be linked to a Twitter campaign to release her husband.
Samar Badawi is believed to have been arrested on Tuesday by Saudi authorities, according to Amnesty International and Badawi's wife Ensaf Haidar.
Samar Badawi - a prominent Saudi human rights advocate - was accused of handling Waleed Abu al-Khair's Twitter account and campaigning for his release.
Waleed Abu al-Khair, who is a human rights lawyer and head of the Saudi Arabia Monitor of Human Rights, is currently serving a 15-year sentence for charges related to defending Raif Badawi, who is currently serving a 10-year sentence for insulting the religion of Islam.
Amnesty International has condemned the arrest, saying on Tuesday that Samar Badawi's arrest was "further damning proof of the authorities' intent to suppress all signs of a peaceful dissent."
