A 39-year-old Japanese woman has been arrested on suspicion of making death threats against two federal court employees in Queensland, according to a local news media report Tuesday.

Australian Associated Press said Megumi Ogawa was arrested Monday for allegedly using a courier service in May to threaten Tim Conrad and Jane Mussett, who work for the Federal Court in Brisbane.

Australian Federal Police allege Ogawa made the threats during more than 150 phone calls to Federal Court staff in May, the report said.

Her arrest came less than three days after being released from a detention center in Sydney, where she was held for a visa violation.

She had been detained at the center since May, having lost her student visa after an enrollment dispute with the University of Melbourne. Her address is listed on court papers as the University of Queensland.

Her deportation was delayed last week after she lodged an application for asylum -- a visa usually reserved for those fleeing persecution.
