Sharipov blamed the Islamic Movement of Uzbekistan (IMU), saying four IMU "associates" had been arrested, and two other suspects were still at large.
The blasts rocked Tajikistan's capital Dushanbe in January and June 2005. One man was killed in January's explosion.
The IMU, banned in many countries and identified as a terrorist organization by the U.S. State Department, was set up in the 1990s with the aim of creating a caliphate in Uzbekistan and other Central Asian states.
