The Tokyo District Public Prosecutor's Office mistakenly faxed a witness account about indicted lawmaker Muneo Suzuki's bribery case to a Tokyo real estate firm in June, a top official of the office said Tuesday.

The fax was supposed to be sent to a prosecutor in charge at the Tokyo District Public Prosecutor's Office, but an official from the office, who was in Obihiro, Hokkaido, at the time, accidentally faxed it to the wrong recipient, Kenichi Sado, deputy head of the office, told a news conference.

The phone numbers were apparently similar, he said.
