Surveillance video from inside Lima's Miguel Castro Castro prison, where van der sloot is being held in the death of Peruvian student Stephany Flores, purportedly shows the young Dutchman trying to buy marijuana.

The grainy footage is believed to show a shirtless van der Sloot standing outside his cell when a drug dealer walks up to him and asks if he wants to buy some pot, according to CNN, which says the footage comes from Peruvian television station, America TV.

According to the video, van der Sloot answers, "Can you sell it to me for five soles[$1.80]?"

RadarOnline reports that the drug dealer was actually an officer of the National Penitentiary Institute.

"Those involved in the shameful fact are fully identified on the tape and will be brought to justice," a source told the website.

Van der Sloot's attorney, Maximo Altez, says the whole thing was "staged" and he has asked Peru's National Correctional Institute to investigate how the tape was made and how it was leaked, according to Radar.

Altez told CNN that his client had been granted permission to paint his cell and that was why his shirt is off in the video: "He took off his shirt so that he wouldn't paint his clothes. He is painting and the guards are talking to him."

Van der Sloot is being held for the death of the 21-year-old Flores, whom he confessed to fatally beating, strangling and suffocating in his Lima hotel room, according to transcripts of his signed confession. He has since recanted in an interview with a Dutch newspaper, and has attempted - thus far unsuccessfully - to have the confession suppressed for a variety of reasons.

Flores' death occurred five years after Alabama teen Natalee Holloway disappeared in Aruba, a case in which van der Sloot is the main suspect.

The Dutchman faces charges of first-degree murder and robbery for the May 30 death of Flores.
