Armenia’s Special Investigative Service (SIS) has filed a petition to detain former Deputy Prime Minister Armen Gevorgyan, charged with obstructing justice in the wake of Armenia’s disputed 2008 presidential election.

Gevorgyan stands accused of pressuring a member of the Armenia’s Constitutional Court to uphold the official election results that recognized Serzh Sargsyan as president.

At the time, Gevorgyan was chief of staff for outgoing president Robert Kocharyan.

The SIS decided to prosecute Gevorgyan last August, citing a leaked U.S. diplomatic cable, but did not arrest him.

Gevorgyan has since promised not to flee Armenia.
