The Tokyo District Court has decided to allow former Construction Minister Eiichi Nakao to be detained for another 10 days through July 11, sources said Sunday.

The veteran Liberal Democratic Party member was arrested Friday on suspicion of accepting some 30 million yen in bribes in 1996 from Tokyo-based construction firm Wakachiku Construction Co. in exchange for using his influence to have the firm selected as a designated bidding company for public works projects.

Nakao was serving as construction minister in 1996.
