She said it in a phone talk on air of 112 Ukraine TV channel, Censor.NET reports citing Interfax-Ukraine.
"I was not arrested. It was a voluntary appearance. Not for a day did I leave the territory of Ukraine. I've permanently stayed with my family and actively cooperated with investigation. Today, I was approached by representatives of counter-intelligence who asked me to come to prosecutor's office for investigation. At present, I am here at prosecutor's office, and investigative actions are underway. I think this information [about arrest - ed.] is due to the recent failures by law enforcement," Lukash said.
As previously reported, SBU spokesperson Olena Hitlianskaya said Olena Lukash returned to Ukraine today and was detained by Security Service officers.
