AGENCIES: An Australian reality TV show contestant has been arrested for allegedly assaulting her Tinder date and extorting money from him.

Suzi Taylor, 49, demanded money after arranging through the dating app to meet the man at a Brisbane house on Wednesday, police said.

When he refused to pay, another man allegedly entered the room and assaulted the 33-year-old victim.

Taylor appeared on a hit home renovations show, The Block, in 2015.

On Thursday, she and a 22-year-old man were arrested and charged with extortion, assault, deprivation of liberty and other offenses.

According to Queensland Police, the pair had held the victim against his will and forced him to transfer money into a bank account.

They also allegedly stole his bank card and made a cash withdrawal. Neither amount was made public by police.
