The suspected coup plotters are three army generals and two police generals, said Presidential spokesman Gervais Abayeho. Others are four lower-ranking officers and eight soldiers. The suspected coup leader, Maj. Gen. Godefroid Niyombare, is still at large.
The coup attempt came amid Burundi's turmoil over Nkurunziza's bid for a third term in office. After weeks of street protests against Nkurunziza's efforts to stay in power, Niyombare announced the coup on Wednesday.
Lawyers representing the suspects say officials tortured them during detention.
"They have been beaten, tied with rope and they don't have shoes and shirts," said Miburo Anatole, an official of the Bar Association of Bujumbura. Anatole said he is representing Maj. Gen. Cyrille Ndayirukiye, a former defense minister, and two police chiefs.
Another lawyer, Cyriaque Nibitegeka, said his client, an army official, was forced to confess under gunpoint and had been denied food since the men were arrested.
Despite the failed coup against Nkurunziza, about 30 protesters said Saturday they will continue demonstrating against the leader's bid for a third term, which they say goes against the two term limit set by the constitution.
The protesters defied Nkurunziza's ban on demonstrations and vowed to continue to take to the streets to press the president to drop his plan to run for re-election in June.
"We are going to continue with the protests because our aim is to stop the president's third term. We can see that they are determined to stop us but we are not getting scared and we will not stop the protests. We will continue to fight for the constitution to be respected," said Jean Paul Ndayiragije.
Burundi's election commission said it will review the situation in the coming week to determine whether elections should continue.
