Georgian police say they discovered three unexploded bombs outside the premises of the private Imedi TV station in the capital, Tbilisi.
The Interior Ministry said the explosive devices had been planted by a gang of Georgian suspects run by a Russian military officer who had been arrested over the past three months for allegedly staging a series of blasts in Tbilisi last year, killing one person.
Interior Ministry spokesman Shota Utiashvili said the bombs were planted several months ago, but did not go off and were discovered on February 23 through information provided by the detained suspects.
The Russian officer and another alleged Georgian accomplice are still wanted for questioning by police.
Georgia has often complained of Russian meddling in its affairs since the countries fought a brief war in 2008 over Georgia's breakaway region of South Ossetia.
The Russian Foreign Ministry has described last year's blasts as a "show staged by the authorities in Tbilisi."
