The family of the ousted Egyptian President Mohammed Morsi has accused the army of abducting him, BBC News reported.
His daughter Shaimaa told a news conference in Cairo that the family was taking legal measures against the army.
Morsi has been held at an undisclosed location, without charge, since being ousted from power on July 3.
The family said it held the military responsible for the former leader's "safety and security". The statement is the first from Morsi's family since he was deposed from office.
"We are taking local and international legal measures against Abdul Fattah al-Sisi, the leader of the bloody military coup, and his putschist group," Shaimaa Morsi told reporters.
One of Morsi's sons, Osama, said: "What is going on is a violation of human rights and a scandal in every sense of the word." He described the manner in which the military were holding Morsi as an "abduction".
The family had had no contact with the former president since he was ousted, he said.
Morsi's Muslim Brotherhood movement has refused to recognize the new military-backed administration.It continues to hold almost daily street protests in Cairo.
Several countries, including the United States, have called for Morsi's release. But Egypt's interim authorities insist he is being held in a "safe place".
