"We made a decision to suspend broadcasts, it is our protest. We will not resume broadcasts until the tension and intimidation of our journalists by the authorities has subsided," Georgy Targamadze said.
He also said that staff at the TV channel needed a clear legal status and a stabilized political situation in Georgia before Imedi would go on air again.
Imedi broadcasts were previously suspended on November 7 amid opposition protests for allegedly inciting violence in the ex-Soviet Caucasus republic. A court in Tbilisi ruled to reinstate the TV station's broadcasting license and return its confiscated assets December 11.
Georgian prosecutors insist that Georgian billionaire Badri Patarkatsishvili, who is registered as a presidential candidate, used Imedi to destabilize the country's constitutional system.
Imedi is owned by Rupert Murdoch's News Corp. and, according to some reports, Patarkatsishvili, although the businessman said he had sold his 49% share in the company to the corporation in 2006.
