The KNAB has requested that Magonis be prosecuted for accepting a large bribe, while another individual is suspected of bribing a state official.
Magonis is suspected of accepting a bribe worth €500,000 in connection with a tender for four diesel locomotives organized by the railway company's subsidiary, LDZ Ritosa Sastava Serviss, which was won by Estonian businessman Oleg Ossinovski's company Skinest.
Magonis was detained August 7 last year and in October released on an unprecedented €400,000 bail, the largest in Latvia's history.
