An adult content creator has plunged to her death from the balcony of a hotel after she invited two men to take part in a filmed threesome, prompting an investigation into the mystery death. Anna Beatriz Pereira Alves, who goes by Anna Polly online, was found dead in a courtyard at the aparthotel in Nova Igacu, north-west of Rio de Janeiro. Brazilian police have now launched an investigation into the mysterious death of the content creator.

It is believed that the adult actress fell from the balcony as she filmed steamy scenes with the two men for an online adult content site. The pair reportedly gave conflicting versions of the events leading up to the horror fall, but no arrests have yet taken place. A police homicide unit is analysing hotel CCTV images as part of its investigation and has already questioned the staff. Anna's mobile is also being looked at. The results of a post-mortem carried out have not been made public and it is not yet clear if it showed the presence of drugs in Anna's system or pointed to her being the victim of sexual violence.

Police investigators have described their ongoing probe as "complex" and say they are keeping an open mind on the adult entertainer's death, which they say could be an accident or a crime. A spokesman for the Baixada Fluminense Homicide Unit, which is leading the investigation, told local press: "We are conducting a thorough investigation to clarify what happened. It's a complex case, and we don't rule out any possibility, from an accident to a possible crime.".

The hotel where the incident occurred has been named locally as the four-star Mont Blanc Apart Hotel. Graphic footage showing a police officer standing over a body in a blood-covered sheet, believed to be Anna's, has been published online. "All the information about the case is already in the hands of the police and they are investigating," her boyfriend Pedro Henrique told Brazilian magazine Quem. "If someone is to blame, they will pay and the culprit will be found. She died in the fall. There was no time to save her.".

In a social media tribute where details of her funeral were announced, Pedro said: "It's so difficult without you. As the hours pass it's starting to sink in and the hole in my heart is only getting bigger.". Anna fell to her death on January 23, but despite chatter on social media, her death only reached the mainstream media of her homeland late yesterday. A friend said: "She had loads of plans, she wanted to expand her presence on social media and she always spoke enthusiastically about her future projects. This news has left everyone stunned.".
