The Tokyo District Public Prosecutor's Office has set up a full-time team to investigate the quake-resistance fabrication scandal involving disgraced architect Hidetsugu Aneha, sources said Sunday.

The special team consisting of six prosecutors is expected to work with a joint task force involving several prefectural police forces, they said.

Police investigators raided more than 100 locations, including Aneha's office, in December to look into the data fabrication scandals. There have been no arrests so far.
