YEREVAN.- Director of National Security Service Arthur Vanetsyan and Special Investigation Service Head Sasun Khachatryan were questioned over the wiretapping case, Arthur Vanetsyan told reporters on Thursday.

According to him, he does not interfere with the investigation into the wiretapping case because it can be considered as abuse of power.

Earlier it was reported that  a wiretapped recording of a telephonic conversation between National Security Service Director Artur Vanetsyan and Special Investigation Service Head Sasun Khachatryan was posted on the internet.

In the conversation, they were discussing some particulars of the criminal cases that have been launched into the events that had occurred in capital city Yerevan in March 2008.

On March 1 and 2, 2008, the then authorities used force against the opposition members who were rallying in downtown Yerevan, and against the results of the recent presidential election. Eight demonstrators as well as two servicemen of the internal troops were killed in the clashes. But no one had been brought to account for these deaths, to this day.
