The female suspect held in connection with the mail bombs terror plots aimed at Chicago two places of Jewish worship was tortured and abused during and after her arrest in Sana'a, Hood said on Sunday.

Hanan al Samawi, a fifth-year engineering student at Sana'a University, was violently arrested before her mother and family members, and she was also tortured during investigation by the national security, a source at the organization said.

Meanwhile, law sources expressed concerns about her arrest measures, saying a suspect should be summoned or arrested according to the law.

Hanan's colleagues staged today a sit-in at the engineering faculty and carried placards reading ' we announce our solidarity with Hanan arrested in connection with alleged U.S.-bound mail bombs.'

They urged to release her, saying she had nothing to do with the allegedly suspicious packages, and the Yemeni Student Union called for a strike on Monday in solidarity with Hanan, who was arrested along with her mother on Saturday night and taken to an unknown place.
