Business ombudsman Boris Titov has appealed to federal prosecutors over a group of Russian businessmen currently being held in pre-trial detention.

Russia’s business community has expressed growing concern over the pre-trial detention of U.S. investor Michael Calvey, who has been held on embezzlement charges since Feb. 14President Vladimir Putin on Wednesday called on prosecutors to stop the “groundless extension of custody terms” for businessmen.


“All too often, the decisions of investigators to… extend [detention] periods are absolutely unjustified,” Titov wrote in a letter to Prosecutor General Yury Chaika, the Vedomosti business newspaper reported Thursday.

In the letter, Titov complained that businessmen are being held on embezzlement charges without trial for as long as three years.
