The 11 men are charged with beating the man to death. The charges followed two weeks of questioning, al-Rai newspaper reported on Sunday.
The daily added that the defendants were to appear in a police court for the charges to be read out. The court is an internal body closed to the public.
Interior Minister Samir Habashna said last week the policemen were under formal investigation following the death in September of detainee Abd Allah al-Mashabqa during a brawl between inmates and prison guards.
Any verdict by the police court can be appealed against, he said.
