Natalee Holloway's killer Joran van der Sloot is attacked by inmates in Peruvian jail

Natalee Holloway's Killer Joran van der Sloot has been attacked by other inmates in Peruvian jail. 

The 36-year-old is serving a 28-year sentence for the murder of a Peruvian student in 2010. van der Sloot was also sentenced to 20 years in Alabama last year after pleading guilty to extortion and wire fraud in a plea deal that saw him finally confessing to the 18-year-old missing student's murder. 

The Dutch citizen was attacked by two inmates last week while in a common area of the prison,  where the country's most dangerous criminals are held, as reported by The New York Post.

Other inmates reportedly tried joining the beating before guards broke up the group.

van der Sloot reportedly suffered only bruises and lacerations and received medical care before being sent back to the jail's general population.

A spokesperson for Peru’s National Penitentiary Institute (NPI) told the Post the serial killer will not be punished because he did not start the fight.

van der Sloot's lawyer Maximo Altez told DailyMail.com on Wednesday that he has not been able to confirm the attack took place.

Altez noted that inmates at the remote prison do not have access to phones and rely on letters to communicate. 

Van der Sloot sent a letter to Altez on Sunday and did not report anything outside the ordinary.  

The serial killer was also attacked last year before he was extradited to Birmingham to face on extortion and wire fraud charges pertaining to his attempt to reap a profit from his connection to the Holloway case.

Last year van der Sloot admitted to beating Holloway to death at a beach after she refused his advances and placed her body in the Caribbean.

Five years after the killing, an FBI sting recorded the extortion attempt in which van der Sloot asked for $250,000 from Beth Holloway to reveal the location of her daughter’s remains. He agreed to accept $25,000 to disclose the location, and asked for the other $225,000 once the remains were recovered.

In an interview conducted by his attorney, the killer, who had always denied murdering Natalee, provided details of the final moments of the teen's life.

His sentence for extortion will run concurrently with prison time he is serving for murder in Peru, where he pleaded guilty in 2012 to killing 21-year-old Stephany Flores, a business student from a prominent Peruvian family.

Van der Sloot has been transferred among Peruvian prisons while serving his 28-year sentence in response to reports that he enjoyed privileges such as television, internet access and a cellphone and accusations that he threatened to kill a warden. Before he was extradited to the U.S., he was housed in a prison in a remote area of the Andes, called Challapalca, at 4,600 meters (about 15,090 feet) above sea level.

Holloway went missing during a high school graduation trip. She was last seen May 30, 2005, leaving a bar with van der Sloot. A judge eventually declared her dead, but her body was never found.

Before he could be arrested in the extortion case, van der Sloot slipped away by moving from Aruba to Peru.
