Police are investigating a cast member of Brazil’s most popular reality TV show, “Big Brother Brazil,” for allegedly raping a fellow contestant.

Early Sunday, after a party that was scripted as part of the show, contestant Daniel Echaniz, 31, is alleged to have had sex with Monique Amin, 23, as cameras rolled. Both have denied that to police, they said Tuesday.

“Both of them did confirm they had consumed alcoholic drinks and that they were aware of their surroundings, and they confirmed touching each other under a comforter,” said policeman Antonio Nunes.

Police took the contestants’ underwear and sheets from the show set, and the host voted Daniel off for “inappropriate behavior.”

The party was televised on Brazil’s Globo TV, and showed Echaniz, a model, and Amin, a student, kissing and caressing each other and another image shows Echaniz under the sheets presumably having sex with Amin who appears not to move.

Amin has said she did not recall a sexual act taking place, local media reported.

Network officials told local media that authorities were investigating, because Amin apparently was asleep.

Brazilians for years have been glued to the country’s top reality show which awards a prize worth 830,000 dollars to the winner.
