A UFO enthusiast who mysteriously vanished last week left behind a den plastered wall-to-wall with Illuminati codes and symbols.
Bruno Borges, 24, disappeared from his home in Rio Branco in the west of Brazil having spent the past month working on what is being described as a secret project, according to Daily Mail.
In his furniture-free bedroom, police found a £2000 ($3585) statue of 16th-century philosopher Giordano Bruno who predicted alien life, 14 encrypted books and signs associated with the Illuminati spread across the floor.
He has not been seen since March 27, and his father, local businessman Athos Borges, said he was last seen in a T-shirt and a pair of shorts and would have had no money nor documents.
Deputy Fabrizzio Sobreira, co-ordinator of the Criminal Investigation Office (DIC), who is leading the investigations, confirmed to Acre TV all possibilities are being considered amid speculation he was abducted by the aliens he obsesses over.
Athos Borges, told Globo: "We've tried to call him on his cell phone, but he's off, he's never gone before, he did not take anything and the last time we saw him he was leaving home."
The psychology student went missing shortly after his parents returned from a month-long trip, during which he stayed at home with his sister furiously beavering away at his project.
When his parents left, his bedroom was said to be normal, but 25 days later they were covered in coded writing and symbols as well as 14 secret manuscripts, each with a different Roman numeral on the cover.
His sister, Gabriella, said he would lock himself in the den for hours on end and told Gaucho newspaper: "We were very worried. Now we think he's okay. He has a project, which is the publication of these 14 books. I think he had to do it that way."
