TALLINN, July 29 (RIA Novosti) - Estonian border guards said Tuesday they had detained one of their citizens who lost his passport during a visit to Russia and tried to return home by swimming across the Narova border river.

The 45-year-old man was drunk and soaking wet when he was detained near an Estonian border post after climbing out of the river, which is on average 300 meters wide when it flows between the easternmost Estonian city of Narva and the Russian town of Ivangorod and on into the Gulf of Finland.

The man has been charged and faces a fine if found guilty.
