OSAKA -- A fresh arrest warrant was served Friday on a former senior official of the Osaka High Public Prosecutor's Office on suspicion of accepting bribes from a gangster in return for investigative information, Osaka prosecutors said.

According to the prosecutors, Tamaki Mitsui, 57, is suspected of accepting a gangster's invitation to be entertained in expensive nightclubs in Kobe and Osaka in return for information about an investigation being conducted by the office.

In June and July 2001, the gangster spent about 240,000 yen entertaining Mitsui, they said.
