New breakthrough over death of exotic dancer Stacey Tierney at Melbourne strip club.

There’s been a breakthrough in the mysterious case of British exotic dancer Stacey Tierney, who was found dead in a Melbourne strip club on the morning of Monday, December 19.

According to The Herald Sun, Victorian detectives yesterday arrested and questioned a 33-year-old Ascot Vale man on suspicion to lying to police investigating her death.

The man was released after being interviewed, pending being charged for perjury on summons.

If the man is found guilty of perjury, he could face a maximum penalty of 15 years in jail.

It is believed 29-year-old Stacey had been left dead inside the Dreams Gentlemen’s Club in Melbourne for 12 hours before her body was found.

It's believed the former fitness instructor, who had called Australia home for three years, had partied with "several men" inside the venue before her death.

Authorities suspect Stacey may have consumed illicit substances before her death, with a cover-up attempt made before police were notified.

Police have not yet released the exact cause of the 29-year-old's death.

Victorian police have confirmed they are examining whether drugs were used at Dreams Gentlemen's Club on the night of her death.

"Melbourne Crime Investigation Unit detectives are investigating whether there was drug use at the nightclub on the night of the deceased’s death," police told The Herald Sun.

In January, it was reported that investigations into Stacey's death were focused on the entertainment club’s out-of-hours activities and alleged connections with crime gangs.

When news of her death was revealed, most of Stacey's family had no idea she was working as an exotic dancer.

Police have asked anyone with information on Stacey's death to contact Crime Stoppers on 1800 333 000.
