Lima , Peru ( CNN ) -- Joran van der Sloot has filed a complaint with Peruvian police claiming that his constitutional rights and his right to a defense were violated after his arrest in connection with the killing of a Peruvian woman . According to a copy of the complaint , obtained by CNN , van der Sloot alleges that his right to due process was denied . The complaint , given to the Peruvian National Police 's internal investigation unit , singles out the department 's homicide director , Col. Miguel Angel Canlla Ore , and those who work for him . Van der Sloot said he has been detained without a judicial order . `` I have been denied my right to a proper defense , by imposing an attorney that seems to be the girlfriend of a cop on duty who works in this police department , '' the complaint states . He also alleges that police took his laptop and searched his communications and correspondence without a judicial order . `` I have been imposed an unofficial translator whom has confused me , with the intention of pressuring me to incriminate myself in the homicide investigation , '' the complaint states . The document follows a similar complaint that van der Sloot made to a judge earlier this week . Meanwhile , a judge was expected decide on the legality of van der Sloot 's incarceration Wednesday , his lawyer said . If the ruling is unfavorable , attorney Maximo Altez said he is prepared to appeal to the highest court . Peruvian authorities have charged van der Sloot with murder in the death of 21-year-old Stephany Flores . He also is the lead suspect in the 2005 disappearance of Alabama teenager Natalee Holloway in Aruba . Van der Sloot was arrested twice in connection with Holloway 's disappearance in Aruba but was never charged because of lack of evidence . A court document obtained by CNN shows Flores had a cranial fracture and other significant injuries to her face and neck and showed signs of asphyxiation . Forensic luminol tests in the hotel room where her body was found showed blood on the floors , hallway and mattress , the document said . Altez has maintained that the judge in the case should strike down van der Sloot 's confession because he was not properly represented when he was interrogated . But Peruvian police have defended the interrogation , saying that van der Sloot 's confession was acquired legally . According to transcripts of his confession , van der Sloot said he elbowed Flores in the face before strangling her and then suffocating her with his shirt . The transcripts were provided to CNN by a police source who has not been named because he was not authorized to pass along the material . Van der Sloot told authorities he attacked Flores on May 30 after she read an e-mail on his computer connected with the Holloway case . After killing Flores , police say , van der Sloot took money and bank cards from her wallet and fled to Chile , where he was arrested on June 3 . He was returned the next day to Peru . Van der Sloot is being held in a high-security area of the Miguel Castro Castro prison where only two of 10 cells are occupied , and he has no contact with inmates in the general prison population . He is under guard 24 hours a day , authorities have said . CNN 's Mayra Cuevas contributed to this report .
