JOHN Xydias, who filmed himself as he sexually assaulted 11 unconscious women over a 15-year period, has been jailed.

Xydias videotaped his crimes after drugging his victims.

The Herald Sun reports one of his victims wept in the Supreme Court today as he was sentenced to 28 years in jail, and ordered to serve a minimum of 20 by Chief Justice Marilyn Warren.

His former girlfriend, known only as "Josie", sat behind him in court clutching a gold cross, crying and apearing shocked as details of his offences were read to the court.

A tip-off led police to uncover 17 tapes Xydias had made of his demeaning attacks at his family's Glen Iris home and Dromana holiday house.

He pleaded guilty last year to 66 charges of rape and indecent assault between 1991 and 2006.

Seven victims were known to him when they were assaulted, with four victims captured on film yet to be identified.
