The secretary general of the opposition Social Democratic Party met prosecutors of the National Anti-Corruption Department (DNA) today to learn about the reason he is investigated for acts connected in the bribery case surrounding his former government and party boss Adrian Nastase.

Miron Mitrea, who was the Transport minister in the Nastase government in 2001-2004, said on leaving the hearing that he learned he was investigated for taking bribes in relation to a property owned by his mother.

"Prosecutors asked me about the works at my mother’s house, by a firm of the group of companies held by Sergiu Sechelariu", a local businessman and politician from the region of Moldova.

He said he would prove all the works at the house were legal.

When he first learned from prosecutors that he was investigated by the DNA, Mitrea had said he was not informed about the reasons of the move.

Sechelariu is one of the many people indicted in the so-called Zambaccian case, in which former PM Adrian Nastase and his wife Dana Nastase face graft charges.

DNA head Daniel Morar confirmed on Wednesday that several searches have taken place at a building on the Zambaccian St. in Bucharest, where the Nastase family lives.

He also said a person investigated in the case received threats from unidentified individuals. He refused to reveal the person’s identity.
