( CNN ) -- Authorities in Bahrain said Friday that they 've arrested the daughter of a human rights activist who has drawn international attention and widespread protests with a hunger strike that he 's sustained for nearly two months . Zainab al-Khawaja was detained outside the Interior Ministry complex , said her lawyer , who is also representing her father , Abdulhadi al-Khawaja . Her father is striking to protest the life sentence he received for his alleged role in the unrest that continues to embroil his country . The elder activist was arrested last April for his role in anti-government demonstrations in Bahrain in February and March . In June , he and seven other Shiite opposition activists were found guilty of plotting to overthrow the country 's Sunni royal family . The Interior Ministry said Zainab al-Khawaja was arrested Thursday night after it told her several times that she was in a restricted area `` in which standing is prohibited . '' The ministry also said she `` attacked an on-duty public employee . '' Their lawyer , Mohammed Al Jishi , said she had been calling out for her father , who was at the Interior Ministry complex and was to be moved to a military hospital because his condition was deteriorating . He said that the hunger striker was transferred to the hospital Friday , but that the government had not given his family permission to see him . They were told of the transfer Friday . Al Jishi has expressed concerns that his client could soon die and that the last time he saw him was two days ago . The Interior Ministry 's general inspector said that `` all policies and procedures of the prison facilities in Bahrain meet international human rights standards , and all detainees have consistent and reliable access to professional medical care , '' according to a statement from Maj. Gen. Tariq H. Al Hasan , a spokesman for the ministry . On March 30 , the government reported that Abdulhadi al-Khawaja had low blood pressure and was taken to Bahrain Defense Force Hospital , where he was treated and returned to Jau Prison the following day . Records showed that al-Khawaja had lost about 10 kilograms ( 22 pounds ) and had a low hemoglobin level , though not critically low , the government said . He was also reportedly taking fluids , mineral supplements , glucose and juice on a daily basis . The Bahrain Center for Human Rights , a nonprofit human rights group started by al-Khawaja and for which his other daughter , Maryam , works , has appealed for his immediate release on humanitarian grounds . Demonstrators and Bahraini authorities have continued to clash in recent months , with the opposition accusing the government of using heavy-handed tactics .
