Austrian beauty influencer Stefanie Bieber’s boyfriend and two relatives have been arrested after she didn’t return home from a Christmas party.

An Austrian beauty influencer disappeared while returning home from a Christmas party – and her ex-boyfriend and two of his relatives have now been arrested.

Stephanie Bieber, 32, has not been seen or heard from since she got out of a taxi with her friend at her apartment in Graz, Austria’s second-largest city, on Sunday morning.

Local police said they were unable to take photos the next day.

Local authorities found her dog alone in her apartment and confirmed that her phone was off, according to Austrian news outlet Kurier.

Her ex-boyfriend was arrested after setting his car on fire in a casino parking lot in Slovenia on Monday. Local police said.

“He was found in the immediate vicinity of the burning car and was arrested by Slovenian police. His extradition to Austria was requested.”

Pieper’s location has not yet been determined.

Border crossing data between Slovenia and Austria shows that Bieber’s ex traveled to Slovenia and back several times this week. According to Klein Zeitung.
