Osman Kavala told an Istanbul court the charges against him "are not based on any evidence." He's spent years in pretrial detention, and was arrested again on separate charges hours after a Turkish court acquitted him.
A Turkish court on Friday ordered civil society leader Osman Kavala be kept behind bars on charges he said were based on "conspiracy theories," four years after he was imprisoned without conviction.
He faces a 20-year prison sentence without parole if convicted.
The 64-year-old Kavala himself denied the charges calling them "slanderous" and "an assassination attempt against my dignity."
"It is totally devoid of evidence, just like the accusation of espionage that was fabricated later,'' he told the court.
"What is striking about the charges brought against me is not merely the fact that they are not based on any evidence," he said. "They are allegations of a fantastic nature based on conspiracy theories overstepping the bounds of reason.''

Acquitted over protest, then charged with 'coup' participation instead
At the end of the session, the Istanbul court set a new hearing for November 26, with Kavala ordered to remain behind bars until that date.
European Parliament Turkey rapporteur Nacho Sanchez said Friday's session was "a missed opportunity for authorities to respect their international commitments."
Turkey risks sanctions, potentially even exclusion, from the 47-member Council of Europe when it next meets on November 30 unless Kavala has been released.
Mass arrests were common in the aftermath of the Gezi protests, and even more so in the months and years following the supposed coup attempt, when Turkey jailed almost 80,000 alleged Gulen supporters and suspended or sacked around 150,000 public sector workers accused of ties to the group.
A recent US State Department report singled out suspicious deaths of persons in custody, forced disappearances, torture and arbitrary arrests as NATO member Turkey's most pressing human rights issues.
