Prosecutors had then petitioned the court late on Friday to extend their detention.
Commenting on the court decision,Tate’s lawyer Eugen Constantin Vidineac told reporters:“From our perspective,there are no grounds... for taking this most drastic preventive measure,but it is the judge’s prerogative.”
Prosecutors said the Tate brothers had been under criminal investigation since April.
“The four suspects ... appear to have created an organised crime group with the purpose of recruiting,housing and exploiting women by forcing them to create pornographic content meant to be seen on specialised websites for a cost,” the prosecutors said in a statement late on Thursday.
“They would have gained important sums of money.”
Prosecutors said they had found six women who had been sexually exploited by the suspects.
