Rasul Jafarov was detained during the morning of August 2 on suspicion of tax evasion, illegal entrepreneurship, and abuse of authority.
Baku’s Nasimi Court ordered Jafarov held for three months while the investigation into charges against him is conducted.
Jafarov had already been subjected to a foreign travel ban.
Jafarov’s arrest comes three days after prominent rights defender Leyla Yunus was detained and, along with her husband Arif, charged with treason, tax evasion, and illegal entrepreneurship.
He is board member of “Respublican Alternative” and chairman of “Human Rights Club”.
