The Bachelor in Paradise halted after alleged sexual assault

A spinoff of The Bachelor in the US has halted production over alleged misconduct on set, with one contestant reportedly claiming she was sexually assaulted in a pool.

Corinne Olympios has hired a lawyer to seek legal action against producers of Bachelor in Paradise for letting her engage in sexual conduct while "blackout drunk", according to reports.

"We have become aware of allegations of misconduct on the set of Bachelor in Paradise in Mexico," Warner Bros said in a statement.

"We have suspended production and we are conducting a thorough investigation of these allegations. Once the investigation is complete, we will take appropriate responsive action."

Olympios and fellow cast member DeMario Jackson became involved in the incident reportedly after a "day of drinking".

Jackson is said to remember graphic details of rubbing and touching Olympios intimately, but she says she can't remember anything and was told by her cast mates the next day.

The fourth season of the ABC reality series was set to premiere in the US on August 8, but production has been shut down while the incident is investigated.
