South Cairo Prosecution has renewed the detention of several people on charges of running a Facebook account promoting wife-swapping activities.
Two men and their wives were detained for a further 15 days on Wednesday pending investigations into the case.
Prosecutors previously detained the four defendants for four days pending investigations on charges of prostitution and facilitating prostitution.
The prosecutors say they have found pornographic video clips on the defendants' cell phones. They say the clips are currently being examined by experts.
