Correctional Services said that “matters are under control” at Johannesburg’s Sun City Prison on Wed.
Elvis Presley never left the building or checked out of Heartbreak Hotel. He's simply lying low and ordering room service, die-hard fans insist 30 years after his death.
Sightings of Elvis began being reported almost immediately after he died on August 16 1977, at the age of 42.
According to the Elvis Sighting Bulletin Board (ESBB) website, where Internet users can post when and where they saw him, the King has been spotted everywhere from Oman to Norway and London to Kalamazoo since his death.
He's been seen in supermarkets, swimming pools and in fast-food restaurants, according to the ESBB.
"I was at Costco waiting to buy a Nathan's Hot Dog when I heard the customer behind me softly singing Love Me Tender,"the latest sighting posted on ESBB, reads.
"I turned around to compliment him on his voice and that's when I realised it was the King."
Marilyn - could it be that other immortal star? - wrote on the bulletin board earlier this month: "I never believed Elvis was alive until July 2005, when me, my mother and my grandson were in Burger King in Kalamazoo for dinner.
"I saw Elvis and I know it was him. He was alive and doing fine."
Elvis has been sighted driving a blue race car near Boston, and "dressed as an Arab buying 24 cans of Diet Coke in Carrefour supermarket" in Oman.
But none of the Elvis spotters has ever come forward with proof that they did see him.
Should anyone be able to supply concrete evidence that Elvis still lives, they could scoop a reward of about R21,9million from British bookmaker William Hill.
In the US, about 20million people believe that Elvis - who would be 72 today - is still alive, a survey by the CBS national television network has shown.
Conspiracy theorists say Elvis was working with US drug control agencies and was given an identity change to allow him to live anonymously.
As part of his identity change, he travelled around the world - which would explain the sightings in places as far flung as Muscat, Oman or Norway.
Ardent believers in Elvis' immortality cite what they say is irrefutable proof that his death was faked. His middle name, Aron, was misspelled - with two As - on his gravestone, they point out. The coffin was too heavy for it to be Elvis, some say. Too light, say others.
He sang Blue Christmas shortly before he died - his way of warning his fans that he wouldn't be around to celebrate the end-of-year holiday, others say.
In Norway, Elvis was spotted under someone's bed eating a pizza. He shared it.
In Berlin, Elvis was seen in a delicatessen "buying an extra large pastrami on dark rye, pickles and chips". - Sapa-AFP
