Kyiv, July 23 (Interfax-Ukraine) - The Prosecutor General's Office does not rule out that MP Davyd Zhvania from the Our Ukraine-People's Self-Defense Bloc might have been involved in the poisoning of then presidential candidate Viktor Yuschenko in 2004.

An investigator from the office's main investigation department, Oleksiy Donsky, told this to journalists in Kyiv on Wednesday.

"My experience of investigator helps suggest two versions - he [Zhvania] is either afraid of something or somebody in connection with the investigation into this case, or he might be involved in this crime," he said.

Donsky said that "Zhvania arrived at the main investigation department of the Prosecutor General's Office for questioning this morning and left the building two minutes later."

He said that Zhvania had refused to give testimony and "left the questioning session, abusing the status of a people's deputy."

Zhvania, in turn, told journalists that he had refused to give testimony, as he had not been allowed to meet with the head of the investigation group in the case of Yuschenko's poisoning, Halyna Klymovych.

Zhvania said that he had been dissatisfied with the work of the current staff of the investigation group.

"Klymovych is inviting me via the media, but then some of her assistants are speaking with me," he said.

Zhvania also expressed astonishment after he had heard about Yuschenko's statement that the case is being investigated "actively and professionally."

"I was shocked by the president's statement that he was pleased to hear about the questioning of 300 people, and that the president was proud of this," the deputy said.

"This [investigation] has turned into a show," Zhvania said.
