Arkansas Attorney General Dustin McDaniel has demanded documents from five ticket-sales Web sites in an investigation into whether a quick sellout of a "Hannah Montana" concert violated scalping laws.

Venues for the 54-date tour by 14-year-old Miley Cyrus, the star of the Disney Channel show, sold out in as little as four minutes and scalpers are getting four to five times the face value, creating a torrent of complaints from frustrated parents. A single ticket for the show in Charlotte, N.C., sold for $2,565.

"We knew it was hot, but we had no idea it was this crazy," said Debra Rathwell, senior vice president of AEG Live, which is handling her tour. "It's like the Beatles."

In metro Atlanta fans have complained that tickets for the November show at the Arena at Gwinnett Center sold out in minutes, but tickets are for sale at inflated prices on Internet ticket sites.

The sold-out "Best of Both Worlds Tour," which begins Oct. 18, follows the release of her double album, "Hannah Montana 2/Meet Miley Cyrus," which has already sold more than 1 million copies since its release in June. The first album, released late last year, sold more than 2 million copies.

Paige Nace, 35, hoped to take her daughter to see Cyrus in Gwinnett. Nine-year-old Arianna had been begging to see her live ever since she started watching the show, Nace said.

"I think that's it's pretty cool she is coming here," Arianna said. "I want to get up onstage and sing with her. Most likely every girl I know likes Hannah."

But in four minutes, tickets to the November show were gone. Nace said tickets were being resold for inflated prices on Internet sites like Craigslist and eBay Inc.'s ticket-reselling subsidiary, StubHub.

"All the ticket brokers and scalpers are trying to sell them for $100-200 a piece," Nace said. "If they would have been face value, I would have gladly gotten them."

Cyrus, daughter of country music singer Billy Ray Cyrus, plays high school student Miley Stewart, who lives a secret double life as a famous pop star, Hannah Montana. Her show reaches 5 million viewers a week.

McDaniel issued a consumer alert Sept. 21 cautioning parents to research who was selling them the tickets before buying them. The Kansas City, Mo., City Council also has said it would look into the sales.

Gabe Holmstrom, a spokesman for McDaniel's office, said the attorney general's office is focusing on whether ticket brokers used computer software to manipulate ticket purchases and essentially cut in line on the Ticketmaster Web site to buy large quantities of tickets.

McDaniel is also investigating whether fictitious tickets are being listed on those sites just to determine whether consumers would buy tickets at higher prices.

McDaniel gave the companies 20 days to respond.

A spokeswoman for ticketliquidator.com, one of the Web sites targeted, said the company had no comment. McDaniel also demanded the documents from StubHub.com, a ticket-reselling subsidiary of eBay Inc.

Sean Pate, a spokesman for San Francisco-based StubHub, said the company would cooperate with McDaniel.

"What's often mistaken about our marketplace is that we procure and price tickets when, to the contrary, we simply provide a secure and managed online marketplace for those who wish to sell tickets they possess," Pate said.
