Aleksei Dressen (born 1968 in Riga) is a former Estonian Internal Security Service officer being charged with treason. He is being charged with cooperating with Russian intelligence service FSB. He is an ethnic Volga German.
During Soviet rule of Estonia, Aleksei Dressen worked as a policeman (militia). In 1993 he started working for the newly founded Estonian Security Police. In 1994 he lost his police ID. A year later there was a disciplinary charge for wrongful conduct at work. This happened several times during his career. In 1999 his salary was cut by 30% for two months.
Despite all this Aleksei Dressen managed to become a director of several different units in the Estonian Security Police.
Aleksei Dressen and his wife Viktoria were arrested on the morning of 22 February 2012 at Tallinn Airport. Viktoria was about to board a flight to Moscow.
