The elections, won by the ruling New Azerbaijan Party, have been criticized by international observers.
Prosecutors said four election officials have also been detained on suspicion of falsifying balloting results and abuse of office.
The move came a few hours after thousands of opposition protesters took to the streets of the capital, Baku, demanding fresh elections.
The Azadliq -- or Freedom -- opposition coalition said its next rally will be on 12 November. It is not clear whether the government will permit it.
