Authorities have launched an investigation into the death of fashion designer Sylvie Cachay following the discovery of her body in an exclusive New York hotel.

The 33-year-old had been staying at the SoHo House hotel in Manhattan on Thursday night, with her body discovered at 03:00.

Police officers and paramedics were called to the 29 Ninth Avenue address, with Ms Cachay declared dead at the scene.

Investigators have since apprehended her boyfriend, whom has been identified as a son of Joseph Brooks, Oscar winning songwriter of ‘You Light up My Life’.

Brooks faced his own legal troubles last year, with the 71-year-old charged with sex crimes stemming from alleged casting-couch assaults on 11 starlets.

He is still awaiting trial.

His son is presently being questioning at the Sixth Precinct station house.

Speaking to the New York Times, a law enforcement office said there “no obvious trauma” on the victim’s body.

He added there was no sign of drug paraphernalia in the room, only what appeared to be full bottles of prescription medicine.

The room was not in any visible sign of disarray.

Bathtub

Ms Cachay was discovered partially dressed – in a black top and her underwear - sitting upright in an overflowing bathtub.

The NYPD said the medical examiner will now determine the cause of death.

The SoHo House has just 24 exclusive rooms offering “a unique combination of luxury and style”.

There are also Los Angeles and London outposts.
