Asma Rayyam said her husband been unjustly and without charges held in prison where she believes his life is under threat over the spread of the novel covid-19 disease in the central prison, Saudi Al Arabiya TV has reported.
The Gulf country has reported 45,439 and 26 deaths as of Monday.
Rayyman argued that her husband remained in detention although he had been acquitted by justice. The woman charged Qatar officials for torturing and blackmailing her husband.
Sheikh Talal is the grandson of the late Sheikh Ahmed Bin Ali Al Thani, the former Emir of Qatar, who ruled from 1960 until 1972.
Sheikh Ahmed was removed from power by cousin Sheikh Khalifa Bin Hamad, the father of former emir Hamad Bin Khalifa and the grandfather of Sheikh Tamim Bin Hamad, Qatar’s current emir.
Authorities have reportedly frozen Sheikh Talal’s assets.
