(CNN) The Mexican national accused of being a Russian agent in the United States was ordered to remain in custody by a federal judge during a hearing Friday in Miami.

Hector Alejandro Cabrera Fuentes, 34, was wearing a tan jumpsuit and was shackled by hands and feet during the proceeding. He had a scruffy beard and appeared relaxed.

During the short hearing, US Magistrate Judge Chris McAliley explained Fuentes' rights to a bond hearing. Fuentes' temporary attorney, federal public defender Bonnie Phillips Williams, said that she has been in contact with his family who needs more time to hire an attorney.
