Bail has been refused for a NSW doctor charged over the alleged sexual assault and genital mutilation of patients.

Graeme Reeves, 58, was arrested at his home in Sydney’s Baulkham Hills on Wednesday morning after extensive investigations into more than 100 allegations of patient misconduct.

The alleged misconduct occurred between 2001 and 2003 at Baulkham Hills and at Bega, on the state’s south coast.

Reeves is now facing 17 charges, including nine counts of aggravated sexual assault, six counts of indecent assault, one count of female genital mutilation and one count of maliciously inflicting grievous bodily harm.

The charges relate to evidence from 10 female former patients.

At Parramatta Local Court on Wednesday, Magistrate James Garbett ordered Reeves be held in custody, refusing bail.

He said he agreed with the prosecution that Reeves could be a flight risk, and that there was a strong chance a significant custodial sentence would be imposed if the charges were proven.

“The allegations are very serious,” Garbett said.

Reeves was expressionless as bail was refused, but then sat with his head in his hands.

He will next appear in Central Local Court in Sydney on November 5.
