The arrests are said to be linked to an independently organised primary vote.
Officers are also understood to have searched the house of the detained democracy activist Joshua Wong, raided a law firm and pressed news outlets to hand over information.
According to local media reports, a US citizen working in Hong Kong as a lawyer on human rights cases has also been detained.
In July, an alliance of opposition parties ran independently organised primaries to see which of their candidates had the best chances in September's election for the Legislative Council, Hong Kong's parliament.
Hong Kong's leader Carrie Lam had warned at the time the primaries could amount to subversion.
Antony Blink, the pick for next US Secretary of State by President-elect Joe Biden, said they were an "assault on those bravely advocating for universal rights".
"The Biden-Harris administration will stand with the people of Hong Kong and against Beijing's crackdown on democracy."
