The retrial of Alaa Abdel-Fattah and 24 other activists, for their involvement in an unauthorised protest last year against military trials of civilians, has been adjourned Tuesday to 17 November.
Defendants are to remain in jail pending the ongoing trial, as lawyers request their release.
Criticism has been on the rise as of late for the continual renewal of preventative detention for defendants in various cases as trials drag on in courts.
Activists inside court tweeted that Abdel-Fattah complained to the judge of their detention conditions, while defence lawyers requested that defendants be released pending thier trials.
According to the tweets, the defendants inside the cage held up signs reading "We demand justice."
On 11 June, they were given 15-year sentences for organising an illegal protest, rioting, destruction of public property and using violence against the security forces.
They were also fined them LE100,000 (about $14,200) each.
Abdel Fattah and three other defendants were released on 15 September on a LE5,000 bail each pending their retrial.
On 27 October, the judge ordered the detention of 20 of the defendants who turned up at court for the retrial.
Abdel-Fattah's sister, Sanaa Seif, and 22 other defendants were also sentenced last month to three years in jail by another court on similar charges of breaching a law which bans protests not previously approved by authorities.
A number of activists, including Abdel-Fattah’s family, have started a hunger strike in protest at the sentences.
