The Internal Security Bureau said that it had detained deputy head of the Border Guard's Armaments, Logistics and Technical Resources Department who formerly was the Border Guard's chief, as well as two representatives of a road construction company on suspicion of financial fraud and violations committed during infrastructure development at Latvian-Russian and Latvian-Belarusian border.
Another Border Guard official, who has not been named, has been charged in the criminal case, the Internal Security Bureau said.
The Internal Security Bureau will not disclose further information for the time being so as not to impede the investigation.
As reported, Garbars retired from the Border Guard this past January.
The law stipulates that the head of the Border Guard is appointed by the interior minister for a term of five years after the candidate has been approved by the Cabinet. Although in 2016 the government extended Garbar's term of office until 2021, Garbars resigned in January after reaching the retirement age.
Garbars, born in 1969, was appointed head of the Border Guard in 2009, before that he was the head of the Border Guard's Riga Administration.
