Porn star Anna Beatriz Pereira Alves, 27, died at the hotel in Nova Iguacu in Rio de Janeiro on January 23.

A police homicide unit is analysing hotel CCTV images as part of its investigation and has already quizzed staff. Anna’s mobile is also being looked at.

“It’s a complex case, and we don’t rule out any possibility, from an accident to a possible crime.”

The Civil Police of the state of Rio de Janeiro is investigating the incident.

Investigators have described their ongoing probe as “complex” and say they are keeping an open mind on the woman’s death, which they say could be an accident or a crime.

An autopsy has been ordered to determine the exact cause of death.

The hotel where the incident occurred has been named locally as the four-star Mont Blanc Apart Hotel.

Her boyfriend, Pedro Henrique said: “All the information about the case is already in the hands of the police and they are investigating.

“If someone is to blame, they will pay and the culprit will be found.”
