WASHINGTON (Reuters) - Ticketmaster has been subpoenaed or received other requests for information from the U.S. Justice Department, the Federal Trade Commission and the New Jersey Attorney General’s office, the company said in an email obtained by an industry blog.

The law enforcement agencies were interested in Ticketmaster’s relationship with its reseller TicketsNow, in particular controversial sales of tickets to Bruce Springsteen shows in New Jersey on May 21 and 23, said the email displayed on TicketNews.com.

“We have received a number of subpoenas and demands for sworn information about TicketsNow and its broker clients,” Ticketmaster said in the email.

“These include formal requests for information and/or subpoenas from, among others, the United States Department of Justice, the New Jersey Attorney General’s office, the Federal Trade Commission and the Canadian Competition Bureau,” the email said.

Ticketmaster confirmed the email was authentic but had no other comment.

Ticketmaster, which is seeking to merge with the world’s largest concert promoting company Live Nation, was besieged by complaints earlier this year when fans of Bruce Springsteen who signed on to Ticketmaster to buy concert tickets were told that they had sold out within minutes. They were instead directed to the reseller TicketsNow which had considerably more expensive tickets.

Ticketmaster has said the problem was caused by a computer glitch.

The Canadian government said last month that it had asked its Competition Bureau to investigate complaints that Ticketmaster diverted tickets to its reselling subsidiary, which then sells them for far higher prices.

In February a Canadian man filed a C$500 million ($407 million) lawsuit against Ticketmaster, charging the company broke the law by reselling tickets at inflated prices.

That same month, Ticketmaster settled with the state of New Jersey to resolve more than 2,000 complaints over how it had handled ticket sales for Springsteen concerts. Canadians, most recently, are complaining about inflated prices to hear Leonard Cohen.
