A House of Representatives committee filed a perjury complaint Wednesday with the Metropolitan Police Department against architect Hidetsugu Aneha on suspicion he gave false testimony to the panel in December about fabricating earthquake-resistance data.
A joint investigative team, which includes Tokyo police, obtained an arrest warrant for Aneha, 49, later in the day for allegedly giving false testimony in the Diet, after the move by the committee.
The House of Representatives Committee on Land, Infrastructure and Transport decided on the move at its meeting earlier Wednesday.
Aneha testified under oath during the December session of the committee that his fabrication of quake-resistance data started in 1998 when he designed a condominium complex in Tokyo's Ota Ward.
However, committee members said they suspected the testimony was untrue and that the fabrication had begun two years earlier.
That suspicion was confirmed by testimony from a senior official from the Land, Infrastructure and Transport Ministry and one from the National Police Agency at a committee session Tuesday.
The infrastructure ministry official said Aneha first fabricated quake-resistance data in 1996 for a condominium complex in Tokyo's Chuo Ward.
Aneha also told the panel in December he had falsified the data under strong pressure from a construction company that was a major client.
