NEW YORK -- Six people were indicted Wednesday in an international ring that took over more than 1,600 StubHub users' accounts and fraudulently bought tickets to such prime events as Jay-Z and Elton John concerts and Broadway shows like "The Book of Mormon," said the Manhattan district attorney, Cyrus R. Vance Jr.

Three others have been arrested in London and one in Toronto, Vance said.

"Today's arrests and indictment connect a global network of hackers, identity thieves and money-launderers who victimized countless individuals," Vance told a news conference.

He said the thieves would resell the tickets bought fraudulently and split up the proceeds. Money stolen in the scheme, in ticket value, was at least $ 1.6 million, he said.

There was RCMP involvement in the move against the alleged international ring.

A release from the New York County District Attorney's Office said RCMP executed a search warrant and arrested a suspected money launderer in Toronto. It said the London arrests were also on suspicion of money laundering.

The release quoted RCMP Inspector Andrew Cowan as saying "organized crime is an international problem that cannot be fought solely within our borders." He called the investigation "an excellent example of the success that can be achieved through strong international partnerships."

StubHub, owned by eBay Inc., is the leading digital marketplace for reselling concert, sports, theatre and other tickets, offering brokers and fans a way "to buy or sell their tickets in a safe, convenient and highly reliable environment," as its website pledges.

StubHub, which is based in San Francisco, said the thieves didn't break through its security; rather, they got account holders' login and password information from data breaches at other websites and retailers or from key-loggers or other malware on the customers' computers, spokesman Glenn Lehrman said.

The company detected the unauthorized transactions last year, he said.

In the last few years, major companies such as Target, LinkedIn, eBay and Neiman Marcus have been hacked.

Since many people use the same passwords at multiple retailers, hackers who get hold of a password for one site often try it at another, Lehrman said.

Authorities generally advise consumers to protect against possible identity theft from such breaches by keeping close watch on their bank statements and using credit card monitoring services, among other tips.
