Woman, 18, drugged, raped by four males: police

Three teenage boys and a man have been charged with allegedly drugging and raping a young woman, then leaving her in a southern Sydney street three months ago.

On a Saturday night in October, it's alleged the 18-year-old woman met a 17-year-old boy known to her at a Lugarno pizza shop, with the pair then meeting up with friends of the boy - another 17-year-old , a 15-year-old and a man, 38.

It's alleged the woman was given an unknown substance and while under the influence, was sexually assaulted several times out the back of the shop.

The Sydney Morning Herald reports a drug was allegedly put in the young woman's wine glass.

She was then dropped off in a Riverwood street several suburbs away and found by a passer-by.

The passer-by called police after seeing the woman wandering around disoriented on the road.

The four males were arrested on Thursday and all charged with aggravated sexual assault in company and refused bail.

The teens will face a children's court on Friday with the man due to face Liverpool Court.
