Former justice minister of Ukraine Olena Lukash, who was detained on Thursday, is being transferred to the Prosecutor General's Office of Ukraine, spokesperson for the Security Service of Ukraine (SBU) Olena Hitlianska has said.

"At the moment counterintelligence officers are taking her [Lukash] to the Prosecutor General's Office of Ukraine to register her detention and to take her testimony," Hitlianska said at a briefing on Thursday.

"This detention will not be the last, we will not talk about the details of the arrest," Hitlianska said.

A video recorded on Thursday was shown during the briefing, in which Lukash states that she has no complaints about her detention.

"Accompanied by counterintelligence [officers] I am heading to the Prosecutor General's Office to give testimony. No pressure was exerted on me," Lukash said.

"This was a normal regular conversation with employees of the counterintelligence [services]," she added.

"I have no complaints, my rights are not [being] violated, and I have volunteered to testify," she said.

Lukash's defense lawyer Andriy Smirnov, in a comment to the Ukrainska Pravda Internet publication, said that Lukash was detained an hour and a half ago.

"She was detained somewhere an hour and a half ago. She was actually kidnapped, because I do not know in which direction my client was taken and where she is now," he said.

Smirnov added that he had called the police and was waiting for them to arrive. He also did not say whether Lukash was abroad before her arrest.
