Joran van der Sloot Update: New Footage Allegedly Shows Prison Drug Deal

LIMA, Peru (CBS) Joran van der Sloot hasn't exactly had a low profile since he was thrown in prison in Peru and charged with killing 21-year-old Stephany Flores in his hotel room - what with reports of love letters from female admirers, stories about his Columbian hitman-roommate, and visits from the mother of his other suspected victim, Natalee Holloway.

Now new footage from inside the prison allegedly shows the young Dutchman trying to buy marijuana from another inmate.

The grainy footage purportedly shows a shirtless van der Sloot standing outside his cell when another inmate walks up to him and calls him "gringo van der Sloot," and asks if he wants to buy some marijuana, according to CNN, which says the footage comes from its Peru affiliate, America TV.

The unidentified man then asks if van der Sloot is "buying."

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

Van der Sloot's attorney, Maximo Altez, says the whole thing was "staged" and he has asked Peru's National Correctional Institute to start an investigation into how the tape was made and how it was leaked, according to the cable news channel.

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."

A spokesman for Lima's Castro Castro prison, Bruno Guzman, said that the matter was under investigation.  "You can see an inmate offering him marijuana," Guzman said. He confirmed that van der Sloot was painting his cell at the time, saying "he wanted to improve his conditions," according to CNN.

Van der Sloot is considered the only suspect, but has not been charged, in the 2005 disappearance of Alabama high school senior Natalee Holloway while on vacation in Aruba.

Meanwhile the investigation into Stephany Flores's death continues, and van der Sloot is waiting for a decision on his appeal to have his confession to police thrown out, on the grounds that his rights were violated.
