An elderly man will have to wait behind bars before the prospect of a sexual assault trial relying on Australia-first forensic technology can begin.
Robert Kwan, 77, was refused bail in the NSW Supreme Court on Friday on charges relating to three alleged sexual assaults committed across the state decades ago.
Kwan is accused of being the same perpetrator behind an assault on an 11-year-old girl in western Sydney in 1991, a 16-year-old girl in Wollongong in 1996 and a 26-year-old woman in Dubbo in 2002.
