Police also say van der Sloot is being held in a cell with a bunk bed and receives three hot meals daily.
Saturday, the 22-year-old Dutchman was swiftly driven in a brown Interpol vehicle into Peru's police headquarters in Peru. He was then briefly paraded in front of the media wearing a bulletproof vest and handcuffs.
Van der Sloot was extradited from Chile Friday, where he was arrested on a murder warrant. He is suspected of killing FLores five years after Holloway disappeared in Aruba after being seen with him, but van der Sloot is proclaiming he is innocent in both cases.
He was arrested in Chile Thursday. He had changed his appearance slighty by shaving his head, but police recognized him right away and extradited him to Peru.
Last Saturday night, van der Sloot was at a casino in Lima, Peru. He sat at the same poker table as Flores, and the two were filmed by security cameras as they entered van der Sloot's hotel.
A few hours later, van der Sloot left. Four days later a maid discovered Flores's body in van der Sloot's hotel room with her neck broken. Van der Sloot told Chilean police that he did not kill Flores, but he did admit that he met her and at some point, they went to a casino.
Five years ago, van der Sloot was the last person seen with Holloway on the night she disappeared in Aruba. Her body has never been found.
Van der Sloot, the prime suspect, was never charged due to a lack of evidence. In Peru, there is no death penalty, but he could face a lengthy prison sentence.
Van der Sloot is also wanted by authorities in Alabama on extortion charges. He's accused there of trying to exchange cash for details on where to find the Holloway's body.
