Dozens of protesters who were detained on 25 January of this year as part of demonstrations to mark the third anniversary of the 2011 uprising were released on Thursday, according to a local rights campaign, Freedom for the Brave.
The group, which campaigns for the release of all political prisoners in Egypt, said that 31 people who were detained during the third anniversary demonstrations were fined LE50,000 each for breaching a protest demonstrations law forbidding unauthorised demonstrations and then released.
The Egyptian authorities have repeatedly denied that there are any political prisoners in the country.
Three days ago, another 21 people detained during the anniversary were also released.
A total of 1,079 "rioters" were arrested across Egypt on the third anniversary of the January 25 revolution, according to the interior ministry.
Security forces said they had prevented "the Muslim Brotherhood's terrorist plot to disrupt celebrations" by "attempting to block roads, chant hostile slogans and provoke riots."
Some of those arrested were accused of possessing Molotov cocktails and fireworks, live ammunition and birdshot rifles.
Freedom for the Brave stated in March that the campaign would file a report with the country's prosecutor-general regarding allegations of torture of detainees in central Cairo's Azbakia police station.
Several detainees alleged they were subjected to torture by security forces during their arrest on 25 January and throughout their detention period, a statement by the group said.
