A business owner will front court accused of drugging and sexually assaulting men he invited to his salon.

Detectives arrested the 39-year-old accused at his business on Friday morning before charging him with two counts of using an intoxicating substance to commit an indictable offence, and two counts of sexual intercourse without consent.

Detectives began investigating in June when two men aged 34 and 37 came forward to allege they had been sexually assaulted at a hair salon on Gardeners Rd in Rosebery, Sydney.

“They were invited to the salon, where they unknowingly ingested a substance before being sexually assaulted,” NSW Police allege.

The man is accused of separate assaults on March 8 and May 25.

He was refused bail and will appear at Bail Division Court 7 on Saturday.
