Erstwhile teachers union boss Elba Esther Gordillo, arrested three days ago on embezzlement and racketeering charges, was moved to a prison with better medical facilities, Mexican authorities said Friday.
Gordillo's personal physician requested the transfer and prison doctors agreed, authorities said, stressing that the labor leader is not receiving any special privileges.
Once considered Mexico's most powerful woman, the 68-year-old Gordillo is said to suffer from high blood pressure, chronic hepatitis C and kidney problems, among other ailments.
She was arrested Tuesday and arraigned a day later on racketeering charges in connection with the alleged embezzlement of $157 million in union funds.
Investigators from Mexico's independent National Human Rights Commission visited Gordillo on Friday after she filed a formal complaint alleging that the arresting officers held her incommunicado and were abusive.
Three other people face charges along with Gordillo.
The SNTE's No. 2 official, Juan Diaz de la Torre, was named Thursday as the new head of the 1.2-million-member-strong union. EFE
